Question

paleontologist lucas e. fiorelli and colleagues have reported the discovery at a mine in brazil of several egg clutches, partially preserved single eggs, and egg shells from the late cretaceous period. the researchers have concluded that the area was once a nesting and breeding site for titanosaurs, a group of sauropod dinosaurs. the finding is significant given the previous lack of known nesting sites in northern regions of south america, which led many paleontologists to assume that titanosaurs migrated south to lay eggs.

what does the text most strongly suggest about the site discovered by the researchers?

a it is the earliest known example of a titanosaur nesting and breeding site.

b it was very difficult to excavate given that it was discovered in a mine.

c it may have been occupied by other sauropods in addition to titanosaurs.

d it is farther north than any other nesting site discovered in south america.

Explanation:

The text states that the finding is significant because of the previous lack of known nesting sites in northern South America. This implies that the discovered site is in the north, and before this discovery, there were no known nesting sites in northern South America. So it can be inferred that this site is farther north than any other previously - discovered nesting site in South America.

• Option A: There is no information in the text about it being the "earliest" known example.
• Option B: The text does not mention anything about the difficulty of excavation.
• Option C: The text only specifically mentions titanosaurs as the assumed occupant of the site.

Answer:

D. It is farther north than any other nesting site discovered in South America.
