The answer to your first question is A - A possible explanation for events using prior knowledge.

Inferring something from data means that we're making a possible explanation for something with using our prior knowledge. 

To answer your second question - the question is stated in a weird way. It could either be B - the amount of soil od D - amount of time. For neither of those does it mention whether or how does the student take them into account. 

I would go with D in the second question however.

A scientist finds the bones of a dinosaur. what could help the scientist determine the approximate age of the dinosaur bones
diamong [38]
The biggest help for the scientists may be provided by the ground layer in which the bones were found. If the layer of ground is not disturbed, than the scientist can easily see the time periods from the structure and color of the ground, and thus determine the time period from when the fossil originates and the approximate age of it.

Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigatio
dedylja [7]

Answer:

C. The songs will become more similar to each other.

Explanation:

To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.

One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.

So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.

The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
