Answer 1

The correct answers are...

detecting a star during the daytime

detecting a star that emits little visible light

detecting stars that are behind nebulae that would normally block out other stars

Step-by-step explanation:

Hope this helps! (:

Answer 2

The answer is; detecting stars that are behind nebulae that would normally block out other stars

Radio waves have large frequencies unlike the other waves of the electromagnetic spectrum. Due to their large wavelength, they are much larger than the size of an atom hence cannot be blocked or deflected by atomic nuclei. This is unlike gamma rays (and other short wavelength electromagnetic radiation) that are smaller than atoms and easily blocked and deflected by atomic nuclei. Such radiations are extremely attenuated when they pass the through nebula cloud. Radio waves hence overcome this challenge.
