'Obfuscate' means to deliberately make something unclear or obscure, often to confuse or mislead.
'Neither' is singular and takes a singular verb. The correct form is 'is acceptable'.
'Acerbic' means sharp and forthright, harsh in tone. This fits with 'offended everyone', whereas other options suggest positive qualities.
'Fewer' is used for countable nouns (apples), while 'less' is used for uncountable nouns (water, sand). 'Apples' is countable, so 'fewer' is correct.
'Ameliorate' means to make something better or improve a situation.
The original sentence uses present perfect tense ('has completed'), so the passive voice should also use present perfect: 'has been completed'.
'Whose' is the possessive form of 'who' and correctly shows possession. 'Who's' is a contraction of 'who is'.
'Prolific' means producing much fruit or foliage or many offspring; highly fertile. 'Scarce' is the opposite, meaning insufficient or rare.
'Ephemeral' means lasting for a very short time. 'Transient' shares this meaning, indicating something temporary or short-lived.
