Your question is missing the options that would allow us to answer properly. After looking it up online, I found these two similar questions. They phrase the sentence just a bit differently, but the message is the same. The options vary, but the correct option is the same for both:
Glen had __________ opportunities to show how __________ he was for being rude to me, but he never even apologized.
brazen...pragmatic
<u>ample...contrite</u>
ostentatious...callous
enigmatic...congenial
Despite having __________ opportunities to show how __________ he felt for being rude to me, Glen never apologized.
perfidious … stoic
deliberate … eloquent
irrevocable … morose
<u>
ample … contrite</u>
Answer:
Glen never demonstrated to me that he was <u>contrite</u> for having been so rude, though he did have <u>ample</u> opportunities to do so.
Explanation:
It is common for a person who has been rude or has done something wrong to feel remorse, guilt, or regret after doing so. In this case, Glen was rude, he felt remorse about it, but he never apologized even though he had plenty of opportunities to do it. The best words to complete the sentence are, therefore, contrite and ample. Contrite means remorseful, full of regret, while ample means enough, plenty, abundant with something.
