The correct answer in 1) is C. delusive. This sentence is trying to describe the brochure; therefore, <u>in order to make a description an adjective is necessary</u>. "Delusive", which refers to something or someone likely to be misleading, is the only adjective among the options provided and that is why option C. is the correct one.
The correct answer in 2) is A. mobility. The sentence needs a <u>noun that refers to the ability of workers to move freely</u> that technology has enhanced in order for them to work from anywhere they are. Nowadays, employees are frequently asked to take assignments that involve moving outside their cities and the word "mobility" contributes to give that meaning to the sentence, unlike "mobile", which refers to a mobile phone, and "mobilization", which means to prepare someone to fight, especially in a war.
Furthermore, the correct answer in 3) is B. altruistic since <u>the noun "ideas", in this case, can only be premodified by an adjective</u>. The only adjective among the options is "altruistic" ("altruism" is a noun and "altruistically", which has been spelled incorrectly in the option, is an adverb).
