1-a, 2- e, 3- b, 4- c, 5 - d

Explanation:

Refracting telescope is used in spy camera as it uses lens to gather and focus light.

Spectrograph separates starlight into wavelengths.

Giant reflectors see behind nebulae dust.

Radio telescope helps in picking up faint lighted stars.

Giant refractors helps to see binary stars.

Hence, 1-a, 2- e, 3- b, 4- c, 5 - d

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
