What area does Marta need further instruction in based on her introduction?

Marta requires further instruction in articles because her introduction likely demonstrates confusion or inconsistency in their use. Articles (such as "a," "an," and "the") play a crucial role in English grammar, helping to clarify the specificity or generality of nouns. If her introduction contains multiple instances of omitted, incorrect, or unclear article usage, it indicates a need for additional practice in this area.

Improving her grasp of articles will enhance the clarity and precision of her writing, allowing her to convey her ideas more effectively. Understanding how to correctly use articles is fundamental for mastering the nuances of English sentences, especially for ELL students who may come from languages that do not use articles in the same way. This foundational knowledge supports their overall language development and academic success.
