2 of 4
read the sentence from the second paragraph of the article. the importance of the balance system is shown by the vast number of connections it makes with the brain. which option best explains how the sentence above supports a central idea of the article?
○ it reveals that good balance can only be achieved when there are a vast number of connections between the environment and the brain.
○ it indicates that the inner ear and the eye are able to achieve balance because of the connections that the organs make to the brain.
○ it indicates that the greater the number of connections made to the brain, the greater the sense of balance that is maintained.
○ it suggests that the balance system maintained by the body is completely dependent on a healthy brain.

Explanation:

• Analyze each option:
• Option 1: The sentence is about the balance system and its connections with the brain, not the environment and brain. So this option is incorrect.
• Option 2: The sentence does not mention the inner ear and eye specifically. So this option is incorrect.
• Option 3: The sentence implies a relationship between the number of connections (of the balance system) with the brain and the importance (which can be related to maintaining balance). This option is in line with the meaning of the sentence.
• Option 4: The word “completely” is too extreme. The sentence just shows a connection, not a complete dependence. So this option is incorrect.

Answer:

It indicates that the greater the number of connections made to the brain, the greater the sense of balance that is maintained.
