Is was she learning a verb phrase?

The sentence "It was she learning a verb phrase?" is grammatically incorrect. Here's why:

* Subject-verb agreement: The subject is "she," which is singular. The verb "was" agrees with a singular subject. However, "learning" is a present participle, which functions as an adjective in this case. The correct verb would be "was learning," not "was she learning."

* Word order: The sentence structure is awkward. The typical word order in a declarative sentence is subject-verb-object.

* Redundancy: "She" is already the subject, so "it was she" is redundant.

Here are some grammatically correct ways to express the intended meaning:

* "Was she learning a verb phrase?" (This is the most direct and natural way to phrase the question.)

* "She was learning a verb phrase." (This is a statement.)

* "She learned a verb phrase." (This is another statement, implying that the learning process is complete.)
