Question

a scientist wrote the following hypothesis: a larger pack improves hunting success. what evidence contradicts this hypothesis?
large packs are more common in areas with lots of prey.
defending pups is more successful in large packs.
the amount of meat each wolf eats is less in larger packs.
in large packs, some wolves dont actually harass and kill prey.

Explanation:

The hypothesis is that a larger pack improves hunting success. If the amount of meat each wolf eats is less in larger packs, it implies that despite the larger pack size, the per - wolf hunting success (in terms of meat consumption) is lower. This goes against the idea that a larger pack improves overall hunting success.

• Option 1 (Large packs are more common in areas with lots of prey) could support the hypothesis as more prey might allow for larger packs, but it doesn't directly contradict the hunting success aspect.
• Option 2 (Defending pups is more successful in large packs) is about a different activity (defending pups) and not about hunting success.
• Option 4 (In large packs, some wolves don't actually harass and kill prey) doesn't necessarily mean the overall hunting success of the pack is not improved. It could still be that the pack as a whole is successful even if some members don't participate in the actual killing.

Answer:

The amount of meat each wolf eats is less in larger packs.
