The following question contains a sentence with a blank. Choose the most…

Concept

A single-blank sentence-completion question is solved by reading the SENSE the sentence already commits to, then choosing the word whose dictionary meaning matches that sense AND whose grammatical fit (collocation, register) is natural. The carrier phrase "promises to ____" frames the technology favourably, so the blank must take a verb with a POSITIVE, improving sense; any word carrying a negative or static sense is ruled out before meaning is even weighed in detail.

Application

The sentence is "The new technology promises to ____ the way we perform everyday tasks." A technology that "promises" something is being presented as a benefit, so the verb must describe making the way we work BETTER or GREATER. The word meaning "to make greater, to increase or enhance" supplies exactly that improving sense and reads naturally after "promises to". So the blank is filled by the verb meaning to enhance/increase.

Contrast

Testing each offered word against the required positive, enhancing sense:

• A verb meaning to hinder or obstruct gives the opposite, negative sense and clashes with "promises".

• A verb meaning to praise publicly applies to people or achievements, not to "the way we perform tasks", so it is a meaning-and-collocation mismatch.

• A verb meaning to stop developing or become inactive is static and negative, the reverse of an improvement.

• A verb meaning to grow worse describes decline, again the opposite of what a promising technology offers.

Only the verb meaning to enhance/increase carries the positive, improving sense the sentence demands, so it is the correct fit.
