Question

the roots \val, valid\ mean...
to strengthen, to give strength
strong
whole, unbroken
to be strong; to be worth

Explanation:

The Latin roots "val" and "valid" are associated with meanings related to strength and worth. The option "to be strong; to be worth" aligns with the etymological meaning of these roots. For example, words like "valid" (having worth or strength in terms of logic) and "valor" (strength of character) derive from these roots, matching this option. Other options like "to strengthen" (a verb form of action, not the root's core meaning), "strong" (an adjective, not the root's base meaning), and "whole, unbroken" (unrelated to "val/valid" roots) are incorrect.

Answer:

D. to be strong; to be worth (assuming the options are labeled A - D with A: to strengthen, to give strength; B: strong; C: whole, unbroken; D: to be strong; to be worth)
