What this part tests

This part is tested with One Choice (Q21–25). Each section below gives the strategy for that question type, the answers, and the sentence that proves them.

Questions 21–25: One Choice

Strategy: Read the question stem and predict the answer before looking at the options. Wrong options often repeat words from the audio while the correct one paraphrases them.

Options for Questions 21–25

  • Asize
  • Bescape
  • Cage
  • Dwater
  • Ecereal
  • Fcalculations
  • Gchanges
  • Hcolour
Q21C — age
“It’s just that they don’t seem to think that science has anything to do with their lives. It’s depressing. They listen to what I say, and I gave them a test last week and the results weren’t too bad, but there’s no real engagement.”

Option C fits: the class sees science as having nothing to do with their lives, so although test results were acceptable, there is no real engagement.

Q22B — escape
“you’d also need to have access to the children’s medical records and I don’t think people would be happy about that; confidentiality would be an issue. If you could get the right data, the conclusions might be significant, but I suspect it’s just not going to be easy.”

Option B fits: getting the children's medical records would raise confidentiality worries, so people would not be happy and the data would be hard to obtain.

Q23A — size
“But if we found out that, say, a particular diet affects the health of animals, the same thing wouldn’t necessarily be true for people, would it?”

Option A fits: a diet that affects animals would not necessarily be true for people, so mouse findings cannot simply be applied to humans.

Q24A — size
“In fact, maybe the focus could be on whether mice can control their own diet.”

Option A fits: she suggests the focus could be on whether mice can control their own diet, meaning the mice choose what they eat.

Q25C — age
“Like, you could give some of the mice the chance to be more active, running on a wheel or something, and the others just sit around and don’t do much.”

Option C fits: some mice get the chance to be more active on a running wheel while others just sit around, so activity levels are varied.
