read the sentence. mark cant come to the movies this afternoon because he helps his brother paint the kitchen. which is the best replacement for the underlined word? helping help has helped is helping
Answer
Brief Explanations:
The sentence indicates an action happening now that prevents Mark from coming to the movies. The present - continuous tense "is helping" is appropriate to show an ongoing action at the present moment. "helping" is a non - finite form and can't be the main verb here. "help" is the base form and doesn't fit the context. "has helped" is the present perfect tense which implies a completed action related to the present, not an ongoing one.
Answer:
is helping
