Final answer:
Sentences 3 and 4 from the article contain central ideas, focusing on the creation process of the Declaration of Independence and the rarity of its original copies respectively.
Step-by-step explanation:
The two sentences from the article that include central ideas of the article are:
- Sentence 3: "The document, central to founding the United States of America, was created through a process that took time cooperation and revision."
- Sentence 4: "It is believed that about 200 copies were published on July 5 and only about 25 still exist today."
The third sentence emphasizes the significance of the Declaration of Independence in the founding of the United States and the collaborative effort it required. The fourth sentence gives historical information about the distribution and the rareness of original copies, reflecting its historical significance and the public's interaction with the document soon after its creation.
