Review: Nanoparticles V
Explanation
In this question, if we again keep the overall message of
the passage in mind, we will gravitate to answer choice (C), as this is the
point of the fourth paragraph. Namely, "Several studies have shown that
nanoparticle design can generate effects not obtained simply by a free ligand
in solution" (lines 36-38). A "free ligand in solution" is equivalent to "those
same ligands without nanoparticles," so choice (C) is right on the mark. Each
of the other answer choices has an objective defect; for example, regarding
(B), the passage describes the death of cells and the creation of tissues, but
not the creation of cells or the death of tissues.
The correct answer is (C).
