Question

during the 2012 restoration of the teatro calderón in valladolid, acoustic tests showed that the renovated main hall produced reverberation times ____ those measured before renovation. engineers attributed the difference to redesigned wooden paneling and altered ceiling curvature, which changed sound dispersion across the 1,100 - seat auditorium.
which choice completes the text so that it conforms to the conventions of standard english?
a more uniform than
b more uniform compared with
c more uniform than that of
d more uniform compared to

Explanation:

To solve this, we analyze the comparison structure. The sentence compares "reverberation times" (plural) after renovation with those before. Option A uses "more uniform than" which correctly compares the two sets of reverberation times. Option B's "compared with" is less standard for this comparative structure. Option C's "that of" is incorrect as "reverberation times" is plural, so "that" (singular) doesn't match. Option D's "compared to" is less appropriate here than "than" for a direct comparison of adjectives (uniform).

Answer:

A. more uniform than
