Question #N33

The author of the passage is arguing that there is a relationship between the brain’s capacity for complex thought and the presence of LINE transposons in the genome. The author suggests that the finding of an active LINE transposon in the genomes of octopus species, which are known for their intelligence, could support this idea. Which choice best describes the author’s main point?

What is the author’s main point?

A. The discovery of an active LINE transposon in the genomes of octopus species supports the theory that LINE transposons are a crucial part of complex cognition.

B. Although LINE transposons are active in the genomes of many species, they are not typically found in the genomes of octopus species.

C. The discovery of LINE transposons in the genomes of octopus species provides evidence that complex cognition is a relatively recent evolutionary development.

D. The presence of LINE transposons in the genomes of octopus species is a sign that these animals are more closely related to humans than scientists previously believed.
