A student investigated the time taken to catch a falling ruler to measure reaction time. The student caught the ruler at the 15 cm mark. Which factor would increase the distance the ruler falls before being caught?

Q: How do I try a free CIE Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A student investigated the time taken to catch a falling ruler to measure reaction time. The student caught the ruler at the 15 cm mark. Which factor would increase the distance the ruler falls before being caught?

Accepted Answer

alcohol consumption before the test — Award 1 mark for recognizing that alcohol slows reaction time by depressing nervous system activity, causing the ruler to fall further before being caught. A is incorrect — caffeine is a stimulant that typically speeds up reaction time. B is incorrect — practice may improve reaction time through familiarity. D is incorrect — increased concentration would decrease reaction time and the distance fallen.

Answer

caffeine consumption before the test

Answer

repeating the test multiple times

Answer

increased concentration during the test
