Question

read the conclusion.
the spiders behavior might have changed over time as a result of living in the cave.
which selection from the article provides the best support to the statement?
a the scientists have suggested that the spiders may not be able to see well enough in the very dark cave to even know there is another spider hanging around.
b she says it is more likely that the larger spiders evolved or simply got used to responding only when the small flies land on their silken webs. maybe they dont attack other spiders.
c the giant web was first discovered in 2009 in a cave of cueva de la osera near the town of algar de palancia, in southeastern spain by a researcher who studies caves.
d the team studied only two species. the researchers still arent sure whether the other kinds of spiders behavior. theyre going to check around again, to see if other spiders also build enormous sheets of silk in caves.

Explanation:

To support the statement that spiders’ behavior changed over time due to living in the cave, we analyze each option:

• Option A: Discusses spiders' vision in the dark, not behavior change over time from cave living.
• Option B: States spiders "got used to" (adapted over time) responding only when small flies land on their webs and maybe not attacking others, showing behavioral change due to cave living.
• Option C: Is about the giant web's discovery, not spider behavior change.
• Option D: (Partially visible, but from context) Likely about study methods, not behavior change.

So Option B provides the best support.

Answer:

B. She says it is more likely that the larger spiders evolved or simply got used to responding only when the small flies land on their silken webs. Maybe they don’t attack others now.
