Explanation
The sentence establishes a sharp contrast between the "unassuming designations" and the "extraordinary precision" of the work these enzymes perform.
Because the names are so simple, they do not accurately reflect the high level of complexity and accuracy involved in DNA proofreading. The blank needs a pair of words that describe how these plain names fail to represent or actually hide the impressive reality of the enzymes.
Belie (D): This means to misrepresent or give a false impression of something. The simple names "belie" the complexity of the actual process.
Obscure (E): This means to conceal or hide. The unassuming labels "obscure" just how precise the enzymes really are.
Annul (A) and Preclude (B): These mean to cancel out or prevent. Names cannot prevent or invalidate the biological precision of an enzyme.
Temper (C): This means to moderate or soften. A name doesn't make the precision of an enzyme "less" precise.
Underscore (F): This is the opposite of what is needed. It means to emphasize or highlight. Simple, "unassuming" names do not highlight or draw attention to extraordinary complexity; they do the opposite.
Answer: D,E

Explanation
The sentence describes the "unassuming designations" given to DNA proofreading enzymes names so plain they are "cataloged merely by Greek letters." These simple names "serve to ______ the extraordinary precision" of the enzymes' work. The contrast is between the plainness of the names and the impressive reality of the function. The blank must mean conceal, hide, or give a false impression of.
The correct pair must be tight synonyms that both describe a deceptive contrast between appearance and reality.
- A. annul - To declare invalid; to cancel, nullify. "Annul" means to legally or formally abolish. Names do not annul precision; they merely conceal it. Incorrect.
- B. preclude - To prevent from happening; to make impossible. If names precluded precision, they would stop the enzymes from working - a far stronger claim than concealment. Incorrect.
- C. temper - To moderate, soften, or dilute. "Temper" implies reducing intensity, not hiding or contradicting. Names do not temper precision; they belie it. Incorrect.
- D. belie - To give a false impression of; to contradict appearances; to mask or disguise. "Serve to belie the extraordinary precision" perfectly captures the ironic contrast between plain names and sophisticated function. Correct.
- E. obscure - To keep from being seen; to conceal; to make unclear. "Serve to obscure the extraordinary precision" produces a sentence virtually identical in meaning to the one with "belie." Both describe the names hiding the true precision. Correct.
- F. underscore - To emphasize, highlight, underline. This is the opposite of what the blank requires. If names underscored the precision, they would draw attention to it, not hide it. Incorrect.
