A.I. Explanation:

Option 1: "It is impossible for a person to remember large numerical figures or foreign language poems."

Explanation: The speaker does not claim that it is impossible to remember large numerical figures or foreign language poems. Instead, they provide examples of individuals with photographic memory, indicating that while some cases are impressive, others are questionable. This option misrepresents the speaker's view.

Option 2: "The existence of photographic memory has been undisputedly proven in a number of cases."

Explanation: The speaker acknowledges that there are cases of photographic memory, such as Akira Haraguchi's, but they also express skepticism about other claims, particularly Elizabeth Stromeyer's. This indicates that the existence of photographic memory is not undisputed, making this option incorrect.

Option 3: "Only a few people have a photographic memory and it is limited to remembering numbers."

Explanation: The speaker does not limit photographic memory to only a few individuals or to remembering numbers. They mention both numerical and poetic memory, suggesting a broader scope. This option inaccurately narrows the definition of photographic memory.

Option 4: "Claims of photographic memory should be subjected to close scientific observation."

Explanation: The speaker expresses doubt about the validity of some claims of photographic memory, particularly those that lack rigorous testing, like Stromeyer's. This indicates that they believe such claims should be closely examined, aligning perfectly with this option.
