Final answer:
The sentence given is a compound sentence that uses the conjunction 'or' to connect two complete thoughts, showing a relationship between Kara Zor-El finding a fork and the alternative of eating salad with a spoon.
Step-by-step explanation:
The sentence 'Kara Zor-El needs to find a fork, or she will have to eat her salad with a spoon' illustrates connecting complete thoughts. The conjunction 'or' in this sentence connects two complete ideas that could stand alone as sentences: 'Kara Zor-El needs to find a fork' and 'she will have to eat her salad with a spoon'. This is an example of a compound sentence where each part can exist independently but are joined together to show a relationship between the two actions.
