Apprehend : emancipate : :
a. deflect : reflect
b. imply : know
c. mandate : authorize
d. reprehend : criticize
e. conceal : manifest

Since the words apprehend:emancipate are basically antonyms, they mean completely the opposite, (apprehend means to arrest, limit someone's freedom, whereas to emancipate means to liberate)  we need to find a pair of words which also have opposite meanings.
The correct answer is E) conceal:manifest. Conceal means to hide, and manifest to show, so you can see they are opposite.

the answer will be option a, credible, creditor, incredible Because all three words share the same root credi-. credi-ble, credi-tor, and in-credi-ble. in option b, c, and d, they all have different roots and therefore, this is why option a is the correct answer. have a great day :)
