Multiple choice
  1. same

  2. similar

  3. related

  4. close

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The passage discusses similarities between great apes and humans. The final sentence comparing blood composition requires establishing similarity, not identity. Blood from different primates is not identical (same would mean exact match), but it shares significant biochemical similarities (similar), making it useful for comparative studies. Related and close are less precise terms in this scientific context.

Multiple choice
  1. eyes

  2. hair

  3. wrinkles

  4. brain

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The passage describes physical similarities between humans and great apes. The context mentions features visible on the forehead that both species share. Great apes, like humans, have expressive facial skin including wrinkles on their foreheads. Eyes cannot be on the forehead, hair is present but not the focus, and the brain is internal - not a surface feature.

Multiple choice
  1. conditions

  2. respects

  3. types

  4. factors

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The phrase resemblance in many respects is a standard English idiom meaning similarities in multiple aspects or areas. Conditions refers to states or circumstances, types means categories, and factors are elements that influence something. None of these fit naturally with the verb resemble - you resemble someone in respects (aspects), not in conditions, types, or factors.

Multiple choice
  1. distant

  2. less

  3. most

  4. closest

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Among great apes, chimpanzees are humans' closest living relatives, sharing approximately 98% of DNA. The blank requires a superlative form comparing resemblance levels. Closest is the correct superlative of close. Most would work with a base adjective like similar (most similar), but closest is the proper form when the root word is close.

Multiple choice
  1. think

  2. apply

  3. work

  4. try

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The pollution passage discusses taking action to reduce environmental damage. The phrase work towards reducing pollution is the correct collocation in English - work towards means to make effort to achieve a goal. Think towards, apply towards, and try towards are all grammatically incorrect or nonsensical combinations. The passage advocates active effort, not just thinking or attempting.

Multiple choice
  1. more

  2. just like

  3. similar

  4. better

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The passage compares anatomical features of great apes and humans. The structure are _____ (iii) ______ to ours requires an adjective that can follow this form. Similar works correctly: are similar to ours. More is incorrect because more...to is ungrammatical (more requires than). Just like doesn't work because the structure would be are just like ours (no to needed). Better makes no sense in this comparison context.

Multiple choice
  1. punish

  2. disallow

  3. minimise

  4. neglect

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The pollution passage suggests practical actions for environmental protection. Minimise the use of polythene bags is standard environmental language meaning to reduce or limit usage. Punish is too harsh and doesn't fit individual action. Disallow suggests prohibition which is unrealistic for personal choices. Neglect means to ignore, which is opposite of the intended environmental protection message.

Multiple choice
  1. atmosphere

  2. earth

  3. environment

  4. air

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pollution poses threats to the environment - the natural world that surrounds us. "Atmosphere" is too specific (only the air layer), "earth" refers to the planet itself, and "air" is just one component. Environment encompasses all natural systems including air, water, soil, and living organisms that pollution affects.

Multiple choice
  1. diseases

  2. threats

  3. symptoms

  4. factors

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pollution is described as a threat to the environment. While pollution can cause diseases and might be considered a factor, "threats" best captures the danger and harm posed. The sentence structure "major threats to" is the standard collocation. "Symptoms" would describe effects of pollution, not pollution itself.

Multiple choice
  1. converted

  2. relying

  3. running

  4. burning

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Vehicles and automobiles "running on" eco-friendly fuels is the correct phrase. "Running on" describes how a vehicle operates using a particular fuel source. "Converted on" and "relying on" are grammatically incorrect. "Burning on" is not idiomatic - we say vehicles run on fuel, not burn on fuel.

Multiple choice
  1. explains

  2. gives

  3. means

  4. answers

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The sentence asks what "radioactive" means. "Means" is the correct verb to explain the definition of a term. "Explains" would need the term as subject (radioactivity explains), "gives" doesn't fit semantically, and "answers" would require the term to answer something, which is the opposite of what's happening here.

Multiple choice
  1. tear off

  2. failure

  3. decay

  4. build up

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The text describes how heavy atoms "break down and change into other kinds" and calls this process "radioactivity." This breakdown is scientifically called "decay" - radioactive decay. "Tear off" is too informal, "failure" doesn't describe the transformation process, and "build up" is the opposite of what happens.

Multiple choice
  1. disintegrates

  2. divides

  3. multiplies

  4. freezes

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Each radioactive element disintegrates (breaks down) by giving off rays. "Disintegrates" precisely captures the atomic breakdown process in radioactive decay. "Divides" implies splitting into equal parts, "multiplies" means increasing in number, and "freezes" has no relevance to radioactive processes.
