Question

1. her obvious spirit

a unflagging
b unaware
c plainly clear
d self - confident
e happy - go - lucky

Explanation:

To solve this, we analyze the meaning of "obvious spirit" and match it with the options. "Unflagging" means tireless or persistent, which relates to a strong, obvious spirit. "Unaware" is about not knowing, "plainly clear" is redundant and not about spirit, "self - confident" is about confidence, "happy - go - lucky" is about a carefree attitude. So "unflagging" (A) best fits "obvious spirit" in terms of a strong, persistent spirit.

Answer:

A. unflagging
