Which option correctly marks the main word and asks the question in the phrase: The cat is walking? - in detail

In the sentence "The cat is walking," the primary focus is on identifying the main subject and forming an appropriate question based on that subject. To determine which word is the main one, we need to consider the structure of the sentence and the role each word plays in conveying its meaning.

Firstly, let's analyze the sentence: "The cat is walking." Here, "cat" serves as the subject of the sentence, while "is walking" acts as the predicate. The verb "is walking" describes the action performed by the subject. In English grammar, the main word in a declarative sentence is typically the subject, which in this case is "cat."

To form a question based on the main word, we rearrange the sentence structure. A common way to do this is to place the auxiliary verb (in this case, "is") before the subject. Therefore, the correct question that highlights "cat" as the main word would be: "Is the cat walking?"

This question directly inquires about the state or action of the main subject, "cat," maintaining its prominence in the sentence structure. Alternative formulations such as "The cat is walking what?" or "Walking who?" do not accurately reflect the original sentence's intent and fail to maintain the focus on "cat" as the main subject.

In conclusion, the option that correctly marks the main word and asks the question in the phrase "The cat is walking" is: "Is the cat walking?"
