Answer:
- There he became the school's first African-American student, studied agricultural science, and received a bachelor's degree in 1894.
Explanation:
The given sentence contains a punctuation error and error in use of a conjunction. The aptest version to revise the underlined portion of the sentence would be as mentioned above. The commas and conjunctions are wrongly placed in the given sentence. At the beginning of the sentence, no comma is required after 'there' as it refers to the location. The sentence discusses a list of actions through comma but incorrectly uses coordinating conjunction 'and' before proceeding towards the last action in the list. It can be corrected by removing the conjunction and placing a comma(,) after 'science'. Thus, the final sentence reads as:
'There he became the school's first African-American student, studied agricultural science, and received a bachelor's degree in 1894.'
