Answer:
First Option: The first glasses did not help people who were nearsighted.
Step-by-step explanation:
An inference is a conclusion which we make based on some reasoning or evidence.
In this case, there is an evidence in text that the first eyeglass lenses made of convex glass ONLY helped people who were farsighted. From the word "ONLY" we infer that those glasses did not help people who were nearsighted.
Second Option: The second option,“In the past people who were nearsighted did not need glasses” has no evidence in the text not is it true based on what we already know.
Third Option: It states that,“In the past most people were farsighted”. This too has no evidence in the text not is it true based on what we already know.
