The correct statements are:
1. The dinosaur and the mammoth existed after the trilobites.
The trilobites are a species that appeared and existed much earlier than any dinosaur or later mammals like the mammoth. The difference in their existence is few hundred million years, and while the trilobites are primitive life form, the dinosaurs and mammoths are much newer, better evolved species.
3. The trilobites and the armored fish died before the dinosaur.
Before the dinosaurs appeared, there were many other species that lived before them, some of which are the trilobites and the armored fish. The trilobites being one of the oldest species, and the armored fish being a more evolved but still primitive fish with exoskeleton. Both of them existed in periods prior to the dinosaur domination.

The purpose of the question is to properly identify the tense of the verb being used. For this case, we use context clues to infer that the verb is being used in the present tense and will answer accordingly.
From the sentence given, we can use the word "está" as context to determine the tense of the verb. "Está" is used in the present tense. The other ways to use this word are:
- "Estuvo", signals a past tense of a verb will follow.
- "Estara", signals that a future tense of a verb will follow.
The fact that the previous word is being used in the present tense allows us to infer that the verb will be used in the present tense as well. Therefore, we choose the present tense of the verb "visitar" which corresponds to "visitando" and fill in the blank with this word.

The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
Given an incomplete sentence related to hypothesis and astronomy.
We are required to complete the sentence.
A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.
Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.
The statement can be completed by "do experiments and observations about the prediction of the hypothesis".
Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
