BAND 9

Part 1 · Band 9 Sample Answer

The stacked bar chart illustrates how the percentage of electricity produced from non-renewable sources, hydropower, wind and solar power changed in a country at five-year intervals between 2000 and 2020.

Overall, non-renewable energy remained the largest individual source throughout the period, although its share declined substantially from more than four fifths to just under half. Consequently, the combined contribution of renewables rose from 17% to 51%. Hydropower was broadly stable, so most of this expansion came from increasingly important wind and solar power.

In 2000, non-renewable sources accounted for 83% of electricity generation, while hydropower supplied 15%. Wind contributed the remaining 2%, and there was no visible contribution from solar energy. By 2005, the non-renewable proportion had fallen to 77%. Hydropower edged up to 16%, whereas wind and solar represented approximately 6% and 1% respectively.

The shift became more pronounced thereafter. In 2010, 70% of electricity still came from non-renewables, compared with 16% from hydropower, 10% from wind and 4% from solar. The conventional share then dropped to 58% in 2015 and 49% by 2020. Hydropower changed little, standing at about 17% and 16% in those years. By contrast, wind climbed to 16% in 2015 and 20% in 2020, overtaking hydropower, while solar rose steadily to 9% and then 15%.

BAND 8

Part 1 · Band 8 Sample Answer

The chart compares the shares of electricity generated from non-renewable energy and three renewable sources in a country from 2000 to 2020, with figures shown every five years.

Overall, the country became considerably less dependent on non-renewable sources. Although these still formed the largest single category in every year, their proportion fell to below half by 2020. Renewable electricity therefore grew to a slim majority, mainly because wind and solar power expanded, while the contribution of hydropower was relatively unchanged.

At the beginning of the period, non-renewables produced 83% of all electricity. Almost all the rest came from hydropower, at 15%, since wind supplied only 2% and solar made no noticeable contribution. In 2005, the non-renewable figure decreased to 77%, while hydropower rose slightly to around 16%. Wind and solar then accounted for roughly 6% and 1%.

By 2010, the share from non-renewable sources had declined by a further 7 percentage points to 70%. At that time, hydropower provided 16%, wind 10% and solar 4%. This transition accelerated over the final decade: non-renewables fell to 58% in 2015 before reaching 49% in 2020. Hydropower remained close to one sixth of generation in both years. Meanwhile, wind increased from 16% to 20%, becoming the leading renewable source in 2020, and solar advanced from approximately 9% to 15%.

BAND 7

Part 1 · Band 7 Sample Answer

The stacked bar chart shows the percentage of electricity that a country generated from non-renewable sources, hydropower, wind power and solar power between 2000 and 2020. Data is provided at five-year intervals.

Overall, non-renewable sources supplied the greatest share of electricity during the whole period, but their importance decreased steadily. At the same time, renewable energy rose from a relatively small proportion to just over half of total generation. Wind and solar experienced clear growth, whereas hydropower stayed at a similar level.

In 2000, 83% of the country’s electricity was generated from non-renewable sources. Hydropower made up 15%, while wind represented only 2% and solar was not yet visible in the mix. Five years later, the non-renewable share had fallen to 77%. Hydropower was about 16%, compared with approximately 6% for wind and 1% for solar.

Non-renewable electricity continued to decline, reaching 70% in 2010, 58% in 2015 and 49% in 2020. Hydropower remained quite stable at roughly 16% throughout these later years, apart from a small rise to around 17% in 2015. In contrast, wind increased from 10% in 2010 to 16% in 2015 and 20% in 2020. Solar followed the same upward pattern, growing from 4% to about 9% and finally 15%.

Academic Writing Task 2

Task 2 · Discuss Both Views and Give Your Opinion

Task 2 Prompt

You should spend about 40 minutes on this task. Write at least 250 words.

Write about the following topic:

Many employers now use automated algorithms and artificial intelligence to screen job applications and conduct initial interviews. Some people believe that these technologies can reduce human bias and make recruitment fairer and more efficient. Others argue that they may reproduce or even increase existing social biases because they are often trained on historical data.

Discuss both these views and give your own opinion.

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

BAND 9

Part 2 · Band 9 Sample Answer

Automated recruitment is increasingly used to rank applications and even assess candidates through recorded interviews. Supporters contend that it can make hiring faster and less prejudiced, whereas critics warn that systems trained on previous decisions may perpetuate discrimination. In my view, such technology can improve recruitment, but only when it supports transparent human decision-making rather than determining outcomes independently.

There are persuasive reasons for using algorithms at the initial stage. A large employer may receive thousands of applications for a single graduate programme, making careful manual review both costly and inconsistent. Software can apply the same job-related criteria to every candidate, identify relevant qualifications and remove information such as names or photographs that might trigger conscious or unconscious bias. It can also widen access by processing applications promptly and allowing interviews to be completed remotely. If the criteria are valid and regularly tested, automation may therefore give more applicants a genuine opportunity to be considered.

However, consistency is not synonymous with fairness. An algorithm learns from the objectives and data supplied to it, and historical hiring records often reflect unequal opportunities. For example, a model trained on the profiles of previously successful managers might downgrade applicants whose education, career breaks or vocabulary differ from those of the traditionally dominant group. Video-interview tools may create further problems if they interpret eye contact, facial movement or speech patterns as evidence of competence. Such features can disadvantage disabled candidates, non-native speakers or people from different cultural backgrounds without measuring their ability to perform the job. Because complex models are difficult to explain, rejected applicants may also be unable to identify or challenge an unfair decision.

I therefore believe that employers should use AI for limited tasks such as organising applications, anonymising personal details and flagging candidates for review. Final judgements should remain with trained recruiters, while independent audits should compare selection rates across demographic groups and investigate unexplained disparities. Applicants should also be told when automation is used and offered a human review or an accessible alternative interview format.

In conclusion, recruitment technology can reduce inconsistency and administrative delay, but it does not automatically eliminate prejudice. Its benefits outweigh its risks only when its criteria are relevant, its results are auditable and accountable people retain meaningful control.

BAND 8

Part 2 · Band 8 Sample Answer

Artificial intelligence is now involved in many recruitment processes, from filtering CVs to conducting first-round interviews. Some people see this as a way to reduce personal prejudice and improve efficiency, while others fear that biased historical information will simply be converted into automated decisions. I believe AI can be useful in recruitment, provided that employers monitor it closely and do not allow it to make final decisions alone.

The strongest argument for automation is that it can handle a very large number of applications quickly and consistently. Human recruiters may become tired, overlook suitable candidates or favour people who share their background. In contrast, a well-designed system can assess every application against the same list of relevant skills and qualifications. It can also hide names, ages and photographs during screening, reducing opportunities for discrimination. Employers save time and money, while applicants may receive decisions more quickly.

Nevertheless, an algorithm is only as fair as its training data and design. If a company has historically hired mainly from a narrow social group, a system trained to copy past choices may learn that the characteristics of this group indicate success. It might then reject candidates from different universities, neighbourhoods or career paths even when they could do the work well. Automated video interviews are also questionable when they judge voice, expressions or eye contact. These features may reflect disability, culture or nervousness rather than professional ability. Moreover, when the system is complicated, neither the recruiter nor the applicant may understand why a particular score was given.

For these reasons, AI should assist recruiters rather than replace them. It is suitable for administrative work and an initial comparison of clearly defined qualifications, but humans should review borderline cases and make the final selection. Companies should regularly test whether rejection rates are unusually high for any group and remove criteria that have no direct connection with job performance. Candidates should also have the right to request a human review.

In conclusion, automated recruitment can be faster and more consistent than purely manual hiring, yet it can also repeat discrimination on a larger scale. Careful auditing, relevant criteria and human responsibility are therefore essential if it is to make employment genuinely fairer.

BAND 7

Part 2 · Band 7 Sample Answer

Many companies use algorithms and artificial intelligence to check job applications or carry out early interviews. While some people believe this makes recruitment more efficient and less affected by human prejudice, others argue that the technology can copy unfair patterns from the past. In my opinion, AI is helpful for some parts of recruitment, but people should remain responsible for important hiring decisions.

One advantage of automated screening is its speed. Large organisations may receive hundreds or thousands of applications, and it takes employees a long time to read them all. A computer system can quickly find candidates who have the required qualifications or experience. It can also use the same basic standards for everyone, unlike a recruiter whose judgement may change because of tiredness or a personal preference. If personal details such as names and photographs are removed, the technology may prevent some forms of discrimination.

On the other hand, AI does not make decisions without human influence. People choose the information used to train it and decide which qualities it should value. If most employees hired successfully in the past came from one social group, the system may learn to prefer applicants with a similar background. For instance, it might give a lower score to someone who attended a different type of school or took time away from work to care for children. There are also risks in automated interviews. A system that judges eye contact or speaking style could unfairly disadvantage a nervous candidate, a person with a disability or someone from another culture.

I believe employers should use these tools mainly to organise applications and check clear requirements. A human recruiter should examine the results, interview shortlisted applicants and make the final decision. Companies should also test their systems regularly to see whether particular groups are being rejected more often for reasons unrelated to the job. Applicants need a simple way to ask for human review if they believe the process was unfair.

In conclusion, AI can save time and make some stages of recruitment more consistent. However, it can also repeat existing bias, so it should be carefully checked and used under human supervision rather than trusted completely.
