Question

consider the population of guppies over the time period previously shown. over this time period, guppies with shorter schooling times were more likely to survive and reproduce than guppies with longer schooling times. this means that having a shorter schooling time was more advantageous than having a longer schooling time.
complete the following statements to construct the explanation that is best supported by the information above.
having a shorter schooling time may have been more advantageous than having a longer schooling time because guppies with shorter schooling times were likely to be caught by predators. this may have been because the populations environment had large fish than shrimp.

Explanation:

Since shorter - schooling - time guppies were more likely to survive and reproduce, they were less likely to be caught by predators. If the environment had more large fish (which are likely predators) than shrimp (which may not be major predators of guppies in this context), shorter - schooling - time guppies would have an advantage as they are less likely to be caught.

Answer:

less; more
