For which questions could a scientist develop a testable hypothesis? Check all that apply.Which planet is the prettiest?How long is a day on Neptune?What is the composition of Jupiter’s atmosphere?Do planets prefer being closer to or farther from the Sun?Which planet has the most moons?

A testable hypothesis can be checked using observations or measurements. Neptune’s day length can be measured, Jupiter’s atmospheric composition can be investigated, and the numbers of moons orbiting planets can be compared. “Prettiest” is a matter of opinion, and planets do not have preferences, so those questions are not scientifically testable as written.
