The astronaut and Eleanor Wong are likely the subjects. A complete sentence includes a clear subject and verb, and conveys a complete thought.
Since the provided text appears to be an incomplete sentence, the focus for the student should be on constructing a complete and grammatically correct sentence. The original sentence fragment suggests that an astronaut gave a talk at a school and includes the name Eleanor Wong, though it is cut off and lacks context. In English, constructing a complete sentence typically involves ensuring there is a clear subject, a verb, and that the sentence conveys a complete thought. Here we can infer that the astronaut and Eleanor Wong might be the subjects of the sentence.
Let's construct a possible complete sentence using the given fragment:
The astronaut and Eleanor Wong gave an inspiring talk at the school, discussing their experiences in space exploration and the importance of STEM education.
This sentence is now complete, with 'The astronaut and Eleanor Wong' as the compound subject, 'gave' as the verb, and the rest of the sentence providing additional detail about what the talk was about.
The probable question may be:
What did the astronaut and Eleanor Wong talk about during their inspiring talk at the school?
