Even when the math problems seemed impossible, Maria worked __________ until she understood the difficult math concepts.

Question

BlackTom AI · Accepted Answer

When filling in a sentence like this, we need a word that correctly modifies the verb and fits the grammatical role of the sentence.
Option 1: persistence. This is a noun meaning the quality of continuing to do something; since the blank needs to be an adverbial modifier for 'worked,' using a noun here would create an ungrammatical phrase like 'worked persistence.'
Option 2: persisted. This is the past tense form of the verb 'persist'; 'Maria worked persisted' would be ungrammatical because the participle form cannot directly modify a verb in this construction.
Option 3: persistent. This is an adjective meaning enduring or continuing; while it describes a noun, it cannot properly modify the verb 'worked' in this sentence, so the phrase 'worked persistent' sounds incorrect and awkward.
Option 4: persist. This is the base form of the verb; as with option 2, using the base verb to modify 'worked' is not grammatically appropriate in this context.
Option 5: persistently. This is an adverb meaning in a continuing or enduring way; it correctly modifies the verb 'worked,' yielding a natural, grammatical sentence: 'Maria worked persistently until she understood the difficult math concepts.'
