Question

based on clues in the text, why were scientists likely so surprised when they found quino checkerspot butterflies in the mountains?
the scientists did not think the checkerspots could adapt to colder climates on their own.
the checkerspots made their own way to their preferred plantain plants to lay eggs.
the scientists did not think the checkerspots would be able to avoid detection by new types of predators.
the checkerspots began eating a new plant that was thought to be harmful to them.

Explanation:

To determine why scientists were surprised, we analyze each option:

• The first option says scientists didn't think checkerspots could adapt to colder climates on their own. Mountains are colder, so finding them there would surprise scientists if they doubted this adaptation.
• The second option about moving to plantain plants for eggs doesn't directly relate to surprise at finding them in mountains (no info on mountains and plantain plants' relation to surprise).
• The third option about avoiding new predators doesn't connect to the mountain location context.
• The fourth option about eating a new harmful plant also doesn't tie to the mountain discovery's surprise factor.

So the first option is the most logical as it links the mountain (colder climate) to the scientists' surprise about their adaptation.

Answer:

The scientists did not think the checkerspots could adapt to colder climates on their own.
