Explanation:

1. For the first blank paired with "telescopes": "powerful" is the most precise term to describe advanced, high-capacity astronomical telescopes, as it emphasizes their functional capability to observe distant cosmic objects.
2. For the second blank paired with "light on the vastness...": The phrase "shed light on" is a standard collocation meaning to reveal or explain something, so the correct word here is "shed" (implied by the context of uncovering cosmic mysteries).
3. For the final blank (rightmost dropdown): The context refers to telescopes, so "powerful" is the precise choice to describe these instruments.

Answer:

1. First empty dropdown (after "scrutinizing"): powerful
2. Second empty dropdown (before "light on"): shed
3. Rightmost dropdown (describing telescopes): powerful

Completed sentence:
In the field of astronomy, astronomers peer into the cosmos with powerful telescopes, scrutinizing [celestial bodies] and unraveling the mysteries of the universe, using powerful instruments to measure distant galaxies, shed light on the vastness of the cosmos.
