1. which position of the earth represents an equinox in the figure shown here?

○ a. middle of spring
○ b. beginning of autumn
○ c. beginning of summer
○ d. beginning of winter
□ mark for review (will be highlighted on the review page)

Explanation:

An equinox occurs when the Sun is directly above the equator, leading to nearly equal day and night, happening around March 21 (spring equinox) and September 23 (autumnal equinox). The "beginning of autumn" (23 September) in option B matches the autumnal equinox position. Options A (middle of spring) is not an equinox timing, C (beginning of summer, 22 June) is a solstice, and D (beginning of winter, 22 December) is a solstice.

Answer:

B. Beginning of autumn
