Correct Response: A. English learners develop the ability to use grammatical structures in English more rapidly when there are similar grammatical structures in their first language. Consequently, it is not unusual for an English learner to avoid using a particular grammatical structure in English when it is absent in the first language. The student may require additional practice in order to fully comprehend the meaning or function of the new structure and feel confident about using it. B is incorrect because, in this scenario, the student has avoided only one particular grammatical structure that has been taught but is not avoiding others that have been taught and corrected. C is incorrect because a lack of early exposure to an English learner's first language will not cause the student to avoid only one particular grammatical structure that has been taught in English. D is incorrect because, although teacher self- reflection is an important step, it would not be the most appropriate first step in this scenario.
