English

The preposition 'in' is used to indicate the amount of time before something happens, so 'in five or ten minutes' correctly expresses when the speaker will be finished.

The word "paucity" means scarcity or lack of something. Its antonym is "surplus," which means an excess or abundance, making option B correct.

Acerbity refers to a sharpness or bitterness in tone or taste. Tartness, astringency, and sourness all relate to sharp or biting qualities, making all these options correct synonyms of acerbity.

"Minuscule" means very small, and options A, B, and C (Diminutive, Lilliputian, Miniature) are synonyms meaning small. "Majuscule" refers to large or uppercase letters, making it the antonym of "Minuscule."

"De novo" is a Latin phrase meaning "from the beginning" or "new." Therefore, the correct answer is B, "New."

An elegy is a mournful poem written to praise and express sorrow for someone who has died, making option A the correct answer. The other options do not fit this definition: 'Oad' is a misspelling of 'Ode', which is a lyrical poem praising something but not necessarily sorrowful; 'Sestina' is a complex fixed verse form; and 'Epic' is a long narrative poem about heroic deeds.

The term 'Omnipresent' means being present everywhere at the same time, which directly answers the question. 'Omnipotent' means all-powerful, and 'Omniscient' means all-knowing, so they are incorrect here.

The antonym of 'credulous' (meaning too ready to believe things) is 'skeptical', which means having doubts or not easily convinced. Therefore, option C is correct.

Both 'Exculpate' and 'Exonerate' mean to free someone from blame or guilt, which are synonyms of 'Absolve'. Therefore, option C, 'Both a & b', is correct.

The idiom "to make amends for" means to compensate or atone for a wrongdoing or damage caused. Option B correctly captures this meaning.
