In a clinical trial, patients with bacterial pneumonia were divided into two groups. Group 1 received antibiotics immediately. Group 2 received antibiotics after 48 hours. Recovery rates were significantly higher in Group 1. Which statement best explains this result?

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

In a clinical trial, patients with bacterial pneumonia were divided into two groups. Group 1 received antibiotics immediately. Group 2 received antibiotics after 48 hours. Recovery rates were significantly higher in Group 1. Which statement best explains this result?

Accepted Answer

Early antibiotic treatment prevents bacterial multiplication and reduces tissue damage — Award 1 mark for recognizing that early antibiotic treatment kills bacteria before they multiply extensively, limiting tissue damage and disease severity. D is incorrect because delaying treatment allows more bacterial reproduction and damage. A is incorrect because resistance development is not related to timing in this context. B is incorrect because the question provides no evidence about immune system differences between groups.

Answer

Group 2 patients had stronger immune systems

Answer

Early antibiotic treatment prevents bacterial multiplication and reduces tissue damage

Answer

Bacteria develop resistance more quickly when antibiotics are given immediately

Answer

Delayed treatment allows the immune system to become stronger
