Both sentences in each pair are grammatically correct. However, there are some differences in meaning.

1. The sentence "Many soldiers died in the Gettysburg Battle" uses "Battle" with a capital letter, suggesting that it is referring to a specific historical event, namely the Battle of Gettysburg during the American Civil War. By capitalizing "Battle," it highlights the significance and importance of this particular battle.

2. The sentence "Many soldiers died in the Gettysburg battle" uses "battle" with a lowercase letter. This phrase suggests a more general reference to any battle that might have taken place at Gettysburg. It does not necessarily refer to a specific historical event.

Regarding the second pair of sentences:

3. The sentence "Dancing is fun" is grammatically correct. It expresses the general idea that the activity of dancing is enjoyable.

4. The sentence "Dance is fun" is also grammatically correct. In this case, "dance" is used as a noun, referring to the activity itself rather than the act of performing it. This sentence carries a similar meaning to the previous one, expressing that the concept of dance is enjoyable.

In summary, both sentences in each pair are grammatically correct, but they may differ in their specific meanings and nuances.
