QUESTION TYPE: Most Strongly (Not)Supported
FACTS:
- At night, crows sleep together in a roost.
- During the day, crows will hunt in an area 100-130 kilometers from the roost.
- Usually, crows stay in the same roost for years.
- Then they move to another which is often within eight kilometers of the old roost.
ANALYSIS: This is a rare question stem. We’re looking for something we can disprove. But this isn’t a “must be false” question, so there’s some possibility that the right answer could be true.
Crows have a wide hunting area, but their new roosts are close to the old ones. So the crows probably aren’t moving because of food; they’re still hunting in the old area.
___________
- We have no idea why crows abandon roosts.
- We have no idea what crows do when food is short.
- Who knows? The range extends as far as 100-130 kilometers, but maybe most hunting is done within eight kilometers.
Eight kilometers was the figure for the distance of the new roost; this answer tries to confuse you by mixing terms. - Same as A. We’re not told why crows leave their roost.
- CORRECT. This is highly unlikely. Crows don’t move far, only about eight kilometers. If their old area was depleted, the new roost is within that area.
