Review: Nanoparticles III
Explanation
In this question, we can start with our knowledge of the
main idea of the passage: the point is that the nanoparticles are not just
benign carriers, as had been previously thought, but rather cause further
effects that may be advantageous. Given that, when the scientists began the
construction of nanoparticles, they thought that the nanoparticles would be
benign carriers. So what did that know that is consistent with that fact?
Choice (E) is consistent: they know that they would carry ligands. According to
the passage, they didn't know (C) and (D), because that finding is new. Choice
(B) has an unclear meaning. Choice (A) is possible but unsupported.
The correct answer is (E).
