Final answer:
Paragraphs 3 and 4 in the account of the Dead Sea scrolls do not support any of the key ideas listed in the options provided. Instead, paragraph 3 provides information about the carbon-14 dating of the scrolls, and paragraph 4 discusses the structure of the account.
Step-by-step explanation:
Paragraphs 3 and 4 in the account of the Dead Sea scrolls do not support the key idea of the account in any of the options provided (A, B, C, or D). Instead, paragraph 3 provides information about the carbon-14 dating of the Dead Sea Scrolls, which determines that they were written or copied on paper made from plants that died between 100 BC and AD 50. This information helps establish the age of the scrolls, but it does not directly support any of the key ideas listed.
Paragraph 4 continues the discussion about the structure of the account, suggesting that the evidence provided in the following paragraphs should support the claims made to build a strong argument. Again, it does not support any specific key idea from the options given.
