Question

what is the relationship between the small river labeled x and river b? river x is a tributary of river b river b is a tributary of river x. river x takes water from river b. there is no relationship between the two bodies of water

Explanation:

To determine the relationship, we analyze the river system. A tributary is a stream that flows into a larger river. From the diagram (and typical river flow logic), River X is a smaller river that flows into River B, meaning River X is a tributary of River B. Let's check the options:

• "River B is a tributary of River X" is incorrect as B is larger (or the main river here).
• "River X takes water from River B" is wrong; tributaries contribute water, not take.
• "No relationship" is incorrect as they are connected.
• "River X is a tributary of River B" matches the tributary definition (smaller river flowing into a larger one).

Answer:

A. River X is a tributary of River B
