Question

artificially delivering biomolecules to plant cells is an important component of protecting plants from pathogens, but it is difficult to transmit biomolecules through the layers of the plant cell wall. markita del carpio landry and her colleagues have shown that it may be possible to ______ this problem by transmitting molecules through carbon nanotubes, which can cross cell walls.
which choice completes the text with the most logical and precise word or phrase?
choose 1 answer:
a conceptualize
b neglect
c illustrate
d overcome

Explanation:

The text talks about a difficulty (transmitting biomolecules through plant cell walls) and a method to deal with it (using carbon nanotubes). "Overcome" means to defeat or solve a problem, which fits the context of dealing with the difficulty. "Conceptualize" is about forming an idea, "neglect" is ignoring, and "illustrate" is explaining with examples—none fit as well as "overcome".

Answer:

D. overcome
