The musician played the guitar __________.

The correct answer is Option (2) → well

An adverb is a word that tells how, when, where or how much something happens. It can also describe an adjective or another adverb, for example she sings sweetly, very hot.

Complete sentence: The musician played the guitar well. The blank tells how the musician played, so it needs an adverb.

Option	What it tells	Example
(1) good	an adjective: it describes a noun, not a verb like “played”	He is a good guitar player.
(2) well (answer)	the adverb of “good”, which has no -ly adverb: in a good or skilful way	Kavya speaks English very well.
(3) goodness	a noun meaning the quality of being kind and honest: it cannot tell how he played	Everyone in the village praised her goodness.
(4) goodly	an adjective, though it ends in -ly: an old-fashioned word meaning large in amount	He saved a goodly sum for his daughter’s studies.
