Read the sentence. after she gave the lecture on molecular geometry, dr. jones realized that she would have to expound on the subject at greater length because the students looked confused and gave blank stares when she asked if there were any questions. what is the meaning of the word expound as it is used in the sentence? to explain in detail to explain with illustrations to explain with proven facts to explain at a quick pace

The best answer to the question: What is the meaning of the word expound as it is used in the sentence, would be: To explain in detail.

Explanation:

The reason for this being the correct answer comes directly from the definition of expound that can be found. Expound is defined as explaining something, be it a concept, or theory, or idea, in greater detail, most likely because the concept, idea, or theory, has not been correctly understood, or there is still a measure of misunderstanding. In this case, Dr. Jones will expound, meaning she will explain in further detail, the topic of molecular geometry because, from the gestures and faces of her students, she knows that there has not been a good grasp of the concepts that she explained before. Not being enough, then, she will have to go into greater depth on the topic to achieve comprehension.
