Let us analyze both sentences one by one.

Sentence A: "There is a lot of water in the swimming pool"
- Swimming pools are typically filled with water for people to swim in.
- It is a common and expected scenario to have water in a swimming pool.
- Therefore, Sentence A makes sense.

Sentence B: "There is a lot of sand in the swimming pool"
- Swimming pools are usually filled with water, not sand.
- While it is not impossible for a swimming pool to contain sand, it is not typical or expected.
- Therefore, Sentence B does not make sense in comparison to Sentence A.

Hence, "There is a lot of sand in the swimming pool" (Sentence B) is the one that does not make sense.<|im_end|>

 Sure, I'd be happy to help! Let me think...

Hmmm... Sentence A says there is a lot of water in the swimming pool, which makes sense because a swimming pool is filled with water. But Sentence B says there is a lot of sand in the swimming pool, which doesn't make sense because swimming pools are typically filled with water, not sand.

Therefore, the sentence that does not make sense is:

B. There is a lot of sand in the swimming pool.
