1. Why are position embeddings necessary in Transformer models?

To reduce model parameters

To replace token embeddings

To give the model information about word order

To improve output formatting

By multiplying them

By adding them element-wise

By concatenating them

By sorting them

5. What aspect of language understanding do position embeddings help capture?
