2 9694/22/O/N/20 © UCLES 2020 Section A Study the evidence and then answer questions 1 and 2. Source A Extract from an environmental magazine There is general agreement that the use of fossil fuels in electricity generation is a major contributor to the carbon dioxide (CO2) emissions that cause global warming. This has led to policies that aim to eliminate fossil fuels as a source of power. In the search for alternatives, it has been argued that wood is a suitably ‘green’ fuel. This seems an odd idea, as wood is simply a pre-fossilised form of coal. However, the argument is that the planting of trees to produce wood reduces CO2 in the atmosphere because trees absorb CO2 and release oxygen. This means that burning wood is ‘carbon neutral’, as the CO2 released by burning will eventually be re-absorbed by new tree growth. Twigs, small branches and sawdust are the most carbon- efficient; they can be turned into wood pellets, which emit less than 100 kg of CO2 per megawatt hour. This is a tenth of the amount of CO2 emitted when coal is burned. Major coal-fired power stations are now being converted to burning wood pellets on the basis that this is a ‘green’ form of energy that will help countries meet climate change targets. Demand for wood pellets will increase massively in the future. Source B Publicity pamphlet for a large wood-pellet fuelled power station Compressed wood pellets will play a vital role in moving away from coal, towards a lower carbon energy future. Deforestation is a valid concern when it comes to using wood as a renewable fuel. However, working forests in the USA are not threatened by deforestation. Annual wood growth in the south-eastern USA increased by 112% between 1953 and 2015. Wood that is commercially valuable for other uses, such as construction, is not used to produce wood pellets. Most of our wood pellets are sourced from the south-eastern USA. Source C Extract from Green Party manifesto Wood is often seen as a ‘green’, carbon-neutral renewable resource, the use of which can help tackle the problem of global warming. However, this may not be the case. If the trees cut to supply wood are slow-growing hardwoods rather than fast-growing pines it will take longer for the CO2 emissions from burning the wood to be reabsorbed from the atmosphere. The time lag between the emissions and their reabsorption will cause ‘CO2 emission spikes’ that will last for decades. This means the devastating effects of global warming are likely to hit the planet long before any improvement is felt. Source D Extract from environmental magazine Many of the world’s forests are privately owned, or are in countries where there is little environmental protection or where this is not well-enforced – for example, the hardwood forests in the marshy land of the south-eastern USA. These forests have historically been of little commercial value, but host dozens of plant species and more than 200 animal species, including muskrats and black bears. Conservationists fear that the demand for wood pellets will encourage land owners to convert these forests into less diverse, faster growing pine tree plantations.

3 9694/22/O/N/20 © UCLES 2020 [Turn over Source E Extract from European Union information leaflet Biomass is a renewable energy source which can be used to produce electricity, heat and liquid fuels for vehicles. It accounts for roughly two-thirds of renewable energy in the European Union (EU). Although biomass can come from many different sources, wood is by far the most common. Under EU legislation, biomass is classified as carbon neutral based on the assumption that the carbon released when solid biomass is burned will be re-absorbed during tree growth. Burning wood emits CO2; this creates a ‘carbon debt’. The ‘carbon pay-back period’ is 5–30 years, depending on the wood used, but can be over 100 years old if old trees are intensively harvested. 1 (a) (i) Identify one feature of Source B that increases its reliability. [1] (ii) Identify one feature of Source B that decreases its reliability. [1] (b) Look at Source B. (i) Identify the conclusion drawn from the statistic quoted. [1] (ii) Suggest one problem with drawing this conclusion. [2] (c) Is Source C an argument? Justify your answer. [2] (d) ‘If land owners wanted to replace their hardwood forests for commercial reasons they would have done so long ago.’ Evaluate the strength of this objection to the point being made in Source D. [3] (e) Suggest two possible explanations for why the burning of wood, rather than the use of other carbon neutral options such as wind power, is the most popular choice for renewable energy in the EU. [4] 2 You are advised to spend some time planning your answer before you begin to write it. ‘Burning wood for power generation will not help to combat global warming.’ To what extent do you agree with this claim? Write a short, reasoned argument to support your conclusion, using and evaluating the evidence provided. [8]

4 9694/22/O/N/20 © UCLES 2020 Section B Read the following passage and then answer questions 3, 4 and 5. 1 It has long been understood that children are easily bored and crave excitement and adventure. There was a time when people were expected to grow out of this. But adults now have the same need for excitement and adventure; this is regrettable. High-adrenalin sports such as skiing are very popular even with people in their fifties and sixties. This adult craving for excitement represents a failure to grow up. 2 Social scientists have noted a shift in the last 15 years, from an employment situation where workers had a secure job for life to one that has been called ‘disorganised capitalism’. In this new situation, people are encouraged to think of themselves as self-sufficient risk-takers, who relish the challenges of an uncertain future. So, rather than having a job for life, young people find themselves in what has been called the ‘gig economy’, in freelance self-employed work such as delivering parcels. Work of this kind has none of the advantages of secure employment, such as paid holidays and sick pay. In order to cope with these new conditions, one needs a risk-taking mindset, which is provided by exciting, adrenalin producing activities. So leisure involving such activities is a preparation for work, not an escape from it. 3 Many areas of natural beauty are threatened by this search for excitement. Mountain areas are disfigured by ski-lifts, and it was recently proposed that a zip-wire be put across a valley in the Lake District, a beautiful unspoilt area in England. This proposal was defeated but other such plans will come from the adrenalin junkies. If we want to preserve the beauty of these areas, we must leave them to the hikers and walkers. 4 These activities that produce an adrenalin rush have to have an element of risk in order to be exciting. This means that injuries are very common, which have to be dealt with by health services. So encouraging these activities increases the workload of health professionals. It is inconsistent for governments to mount health campaigns against excessive eating and drinking and not do the same for activities such as mountaineering, which also pose a risk to health. 5 The stresses of modern life are such that people need a safety valve to escape from them. Activities that produce an adrenalin rush enable people to do this, releasing them from the demands of society. People should not have to rely on these adrenalin rushes to cope with life. So we must instead strive to produce a society where such stresses no longer occur.

9694/22 Cambridge International AS & A Level – Mark Scheme PUBLISHED October/November 2020 © UCLES 2020 Page 2 of 10 Generic Marking Principles These general marking principles must be applied by all examiners when marking candidate answers. They should be applied alongside the specific content of the mark scheme or generic level descriptors for a question. Each question paper and mark scheme will also comply with these marking principles. GENERIC MARKING PRINCIPLE 1: Marks must be awarded in line with: • the specific content of the mark scheme or the generic level descriptors for the question • the specific skills defined in the mark scheme or in the generic level descriptors for the question • the standard of response required by a candidate as exemplified by the standardisation scripts. GENERIC MARKING PRINCIPLE 2: Marks awarded are always whole marks (not half marks, or other fractions). GENERIC MARKING PRINCIPLE 3: Marks must be awarded positively: • marks are awarded for correct/valid answers, as defined in the mark scheme. However, credit is given for valid answers which go beyond the scope of the syllabus and mark scheme, referring to your Team Leader as appropriate • marks are awarded when candidates clearly demonstrate what they know and can do • marks are not deducted for errors • marks are not deducted for omissions • answers should only be judged on the quality of spelling, punctuation and grammar when these features are specifically assessed by the question as indicated by the mark scheme. The meaning, however, should be unambiguous. GENERIC MARKING PRINCIPLE 4: Rules must be applied consistently, e.g. in situations where candidates have not followed instructions or in the application of generic level descriptors. GENERIC MARKING PRINCIPLE 5: Marks should be awarded using the full range of marks defined in the mark scheme for the question (however; the use of the full mark range may be limited according to the quality of the candidate responses seen). GENERIC MARKING PRINCIPLE 6: Marks awarded are based solely on the requirements as defined in the mark scheme. Marks should not be awarded with grade thresholds or grade descriptors in mind.

The statistics are about wood growth only / no statistics are given about the number of trees which have been cut down [1]. It is possible that the number of trees cut down is significantly larger than 112% [1], in which case there could still be a problem of deforestation [1]. The meaning of ‘annual wood growth’ is unclear [1]. We don’t know, e.g. if this growth is taking place in ‘working forests’ [1], or if the growth has occurred in the type of trees that would be used for making wood pellets [1], etc. This conclusion is drawn on the basis of figures that apply before there was a demand for wood pellets [1]. Given the evidence about future demand for wood pellets it is possible that these forests will in fact suffer from deforestation in the future [1]. 2 1(c) 2 marks for a correct answer with accurate explanation 1 mark for a correct answer with vague, incomplete or generic explanation 0 marks for a correct answer without explanation 0 marks for an incorrect answer with or without explanation 2-mark answer Source C is an argument. The conclusion is ‘this may not be the case’ / is the second sentence. The following sentences provide reasons (and an IC) to support this conclusion. 1-mark answers Source C is an argument, because it consists of a persuasive conclusion supported by reasoning. Source C is an argument. The conclusion is ‘this may not be the case’ / is the second sentence. Source C is an argument. The conclusion is the final sentence, supported by…….. 0 mark answer Source C is an argument. The conclusion is the final sentence. 2 1(d) Not strong [1]. Clearing these forests to plant other trees before the demand for wood pellets would not have been commercially viable [1]. The point the passage is making is that the demand for wood pellets creates a situation where clearing these forests may become a commercially viable operation [1]. 3

This would mean wood as an energy source was readily available [1]. • The EU may have plentiful supplies of wood with a short carbon pay- back period [1]. This would increase the credibility of wood as a carbon- neutral energy source [1]. • Vested interests may have affected the decisions to use wood/define wood as a renewable source of energy [1]. Countries with large supplies of wood may have been in the most influential position when decisions were made [1]. • Other sources of renewable energy might be expensive to set up and run [1], whereas wood power could be cheaper to obtain [1] (e.g. by converting coal-fired power stations.) • Anything referring to the paucity/reliability of other clean power sources, e.g. The EU may not be very windy/sunny/tidal [1], whereas wood is plentiful [1]. 4

OR Evidence [1] that the search for excitement threatens areas of natural beauty [1]. 2 Question Answer Marks 4(a) • Rather than being a ‘failure to grow up’, using adrenalin-producing activities seems to be a necessary part of being an adult in modern society in the reasoning in paragraph 2. • The author suggests that the search for excitement is a product of job insecurity of the last 15 years, but the age groups cited would have been working for a long time during the period when having a ‘job for life’ was common. 2 marks for a clear identification of inconsistency. 1 mark for adequate identification of inconsistent point in paragraph 1 or 2 without clear contrast to the other paragraph. 2 4(b) 2 marks for a valid answer, clearly expressed. 1 mark for a weak attempt at a valid answer. • Reliance on questionable assumption – that the sole or main type of risk is physical risk. • Reliance on questionable assumption – that the possible health benefits / benefits for health resources of these activities do not outweigh the costs. 2 4(c)(i) The reasoning in paragraph 5 relies on the dichotomy whereby either we ‘have to rely on these adrenalin rushes to cope with life’ or we ‘must strive to produce a society where such stresses no longer occur’ [1], but there are likely to be other possibilities [1]. Maximum 1 mark if only one side of the dichotomy is identified. 2 4(c)(ii) This flaw invalidates the IC in paragraph 5 [1], but it does not greatly weaken the argument as a whole, because this IC gives little direct support to the MC [1] The paragraph could support a different IC that would better support the MC [1].

Example 8-mark answers Support (139 words) Children have a short attention span and unless they find something exciting they will not concentrate on what is happening. If school is boring then little will be learnt because their minds will be elsewhere, probably on when the bell will ring to end the day. Given that the main purpose of schooling is to learn, schooling that is not exciting will fail to achieve this main purpose – the time and money society spends on education will have been wasted. But it is not only society that will be negatively affected. Many children will fail to achieve their full potential meaning their lives will be boring and less fulfilled. So being bored at school is not just a temporary phase – it will set the pattern for the child’s entire life. So school should be an exciting experience for pupils. 8

9694/22 Cambridge International AS & A Level – Mark Scheme PUBLISHED October/November 2020 © UCLES 2020 Page 10 of 10 Question Answer Marks 5 Challenge (156 words) School is about preparation for life and equipping children with the attitudes and skills they will need in adulthood. A key lesson is that many aspects of life are boring and that maturity involves being able to complete tasks which one does not like. If school is always exciting it panders to a childish need to be excited rather than preparing children for the realities of life. School will have failed in its central purpose and the time and money spent on education will have been wasted. Children will grow up to be adults who are never contented and this inability to face up to the realities of life is likely to lead to mental illness. As well as being a problem for the individual, this will put a burden on health services meaning less money to spend on education and other services provided by society. So school should not be an exciting experience for pupils.
