Stimulus

Wounds become infected because the break in the skin allows bacteria to enter. Infection slows healing. Often bacteria-killing ointment is applied to wounds after they have been cleaned, but a study at a Nigerian hospital found that cleaned wounds that were treated with honey—which contains significant quantities of bacteria—healed antibiotic ointment and wounds cleaned but not otherwise treated.

What this question is testing

Paradox

Given that...

Bacteria in wounds = bad. Infection = slow healing. Honey = full of bacteria. So honey on wounds should equal disaster, right?

How can it be that...

Honey-treated wounds healed faster than ointment-treated wounds AND faster than just-cleaned wounds. Honey, the thing full of bacteria, beat the stuff specifically designed to kill bacteria.

Evaluate / Goal

This is a two-part puzzle: (1) why does honey's bacteria not make things worse? and (2) why does honey make things better than antibiotics? The correct answer needs to handle both. An answer that only explains why honey is not harmful, without explaining why it is better than ointment, only gets halfway there.

Which one of the following, if true, most helps to resolve the apparent discrepancy between the results of the study and the stated facts about

Answer choices

  1. Irrelevant Comparison1% picked this

    Wounds that have simply been cleaned with soap and water and not otherwise treated heal faster than wounds that have been cleaned

    This answer tells us that simply-cleaned wounds heal faster than ointment-treated wounds. While this is an interesting finding, it does not address the core paradox — why honey, despite containing bacteria, helps wounds heal faster than either alternative. If anything, this deepens one mystery (why ointment seems to slow healing compared to no treatment) while completely ignoring the honey question. We need to know why honey works, not just that ointment does not.

  2. No Impact4% picked this

    The bacteria found in honey are present in much lower concentrations than the concentrations of bacteria typically present in infected wounds, and applying antibiotic

    This answer offers two facts: honey's bacteria are in lower concentrations than those in typical infections, and ointment rarely kills all bacteria. While these seem helpful at first, neither resolves the paradox. Lower concentrations of bacteria still means more bacteria being added to a wound — any additional bacteria should slow healing according to the stated facts. And ointment not killing all bacteria does not explain why honey (which adds bacteria) heals wounds faster. We need an explanation for honey's positive effect, not just a reduction in its expected negative effect.

  3. Correct76% picked this

    Honey has properties that inhibit the growth of bacteria in wounds, including the bacteria the honey contains, and antibiotic ointments damage sensitive

    Why this is right

    This answer resolves both halves of the paradox beautifully. First, honey has properties that inhibit bacterial growth in wounds, including its own bacteria. This explains why honey does not cause infection despite containing bacteria — the honey itself neutralizes the threat. Second, antibiotic ointments damage sensitive wound tissue, which slows healing. This explains why honey outperforms ointment — while ointment kills bacteria, it also damages the wound. Honey gets the best of both worlds: it inhibits bacteria (like ointment) without damaging tissue (unlike ointment). Together, these two mechanisms explain why honey-treated wounds heal faster than both ointment-treated and untreated wounds.

    Skill tested: Paradox · how this choice captures the argument's function is the move to repeat next time.

  4. Too Weak11% picked this

    The high concentration of sugar in honey inhibits the growth of bacteria in wounds, including the bacteria contained

    This answer explains why honey's bacteria might not cause infection — the high sugar concentration inhibits bacterial growth, including honey's own bacteria. This resolves one half of the paradox: why honey does not make things worse. But it does not explain why honey heals wounds faster than ointment or faster than no treatment at all. Inhibiting bacteria puts honey on roughly equal footing with ointment (which kills bacteria) but does not explain honey's superior healing. We still need to know why the ointment is doing worse, and this answer does not address that.

  5. Too Weak8% picked this

    The antibiotic ointment used in the study damages sensitive tissue in wounds, which slows healing, but honey does not have this effect

    This answer tells us that ointment damages wound tissue, explaining why ointment underperforms — but it does not explain why honey works. Even if ointment is harmful to tissue, that only explains the ointment-vs-cleaning comparison, not the honey-vs-cleaning comparison. Honey still contains bacteria, and we still need an explanation for why honey-treated wounds heal faster than wounds that were only cleaned. Without accounting for why honey's bacteria do not slow healing, this answer leaves the core paradox unresolved.
