Identify the sentence with the correct adjective or adverb.

(a) I have a little to offer, but you have lesser.

(b) If Dennis were least obnoxious, potential clients might find him more approachable.

(c) I need a haircut badly

(d) The summer solstice is the most longest day of the year.

(a) just needs less not lesser

(b) Not really sure but I think it should be was instead of were. Was sounds better.

(c) This sounds correct to me but not sure if it should have bad instead.

(d) doesn't need most

(a) I have a little to offer, but you have less.

(b) If Dennis were less obnoxious, potential clients might find him more approachable.
(c) I need a haircut badly.
(d) The summer solstice is the longest day of the year.

Note: While (b) can be corrected to "If Dennis was least obnoxious," using "were" is grammatically correct for hypothetical situations. And (c) is correct with "badly" as an adverb, emphasizing the need for a haircut.

The correct sentence with the correct adjective or adverb is:

(c) I need a haircut badly.

The correct sentence with the appropriate use of adjective or adverb is:

(c) I need a haircut badly.

Explanation:

(a) The correct adjective to use in this sentence is "less" instead of "lesser." "Less" is used to compare two things, while "lesser" is used to compare more than two things.

(b) This sentence is grammatically correct. The word "were" is appropriate because it is in the subjunctive mood, expressing a hypothetical or contrary-to-fact condition.

(c) This sentence is correct. The word "badly" functions as an adverb, modifying the verb "need." It indicates that the speaker strongly desires or requires a haircut.

(d) The correct phrase would be "the longest day of the year." Adding "most" is redundant because "longest" already indicates the superlative degree.

Your thinking about a, c, and d are correct.

For b, however, it needs to be "less," not "least."

C is correct.
