Answer:
B). Elijah and his brother quickly built a crude shelter that would keep them warm and dry through the night.
Explanation:
The sentence that best uses the fourth contextual clue defining the meaning of the word 'crude' i.e. 'the quality of being rough in execution' is option B. The sentence gives the appropriate meaning to the fourth clue and states 'Elijah and his brother quickly built a crude(rough or coarse) shelter to protect themselves and keep them warm and dry throughout the night'. The other options do not imply the meaning provided in the fourth clue. Thus, the answer is option B.
