Question

1. what is the central idea of the passage?

a. leonardo da vinci preferred science over painting
b. renaissance artists focused only on religious subjects
c. leonardo used observation and knowledge to improve his art
d. the mona lisa is leonardo’s most successful painting

1. how does paragraph 2 help develop the central idea of the

a. it explains how leonardo earned money
b. it describes how artistic techniques conveyed meaning and emotion

Explanation:

Question 1

To determine the central idea, we analyze each option:

• Option A: There's no indication Leonardo preferred science over painting; he integrated both. Eliminate A.
• Option B: Renaissance artists had diverse subjects, not just religious. Eliminate B.
• Option C: Leonardo used observation and knowledge (like scientific study) to enhance his art (e.g., anatomy in paintings), which aligns with his approach.
• Option D: The passage's central idea is not just about Mona Lisa being successful, but about his artistic-scientific methods. Eliminate D.

Assuming the central idea relates to Leonardo’s artistic methods, paragraph 2 likely describes techniques (e.g., sfumato, anatomical accuracy) that convey meaning/emotion, supporting the central idea of his artistic prowess. Option A (earning money) is irrelevant. Option B matches how artistic techniques develop the idea of his art’s depth.

Answer:

C. Leonardo used observation and knowledge to improve his art

Question 2

(Note: Since the full passage and paragraph 2 are not provided, we assume common contexts about Leonardo's art. Typically, when analyzing how a paragraph develops the central idea (about his art-science integration or techniques), we look at its contribution:

• Option A: Earning money is not a central theme of Leonardo's art focus. Eliminate A.
• Option B: Describing artistic techniques to convey meaning/emotion is a key way Leonardo's work (like Mona Lisa's sfumato) develops his artistic approach, which ties to the central idea of his artistry.

(If more context were given, this could be refined, but based on typical questions, B is a strong candidate.)
