which one is correct:
1. the box contains two slides labeled "A" or "B"
2. the box contains two slides labeled "A" and "B"
# 2 is correct.
However, both sentences need capitals at the beginnings and periods at the ends.
Ms. Sue, is there a rule for this that I can use to justify your answer. I have a hard time convincing a colleague that you are correct.
When you use "or" it means that the two nouns are singular. You have two slides, so they are labeled A and B. This implies that one slide is A and the other slide is B.
Both sentences can be correct, but they convey slightly different meanings.
1. "The box contains two slides labeled 'A' or 'B'": This sentence suggests that the box contains two slides, each labeled either 'A' or 'B'. In other words, each slide can have either 'A' or 'B' label, but not both.
2. "The box contains two slides labeled 'A' and 'B'": This sentence suggests that the box contains two slides, with one slide labeled 'A' and the other slide labeled 'B'. In this case, each slide has a specific label and they are different.
To double-check which sentence is correct, you could physically examine the box and its slides, or you could ask someone who has information about the contents of the box.
