Answer 2

The correct answers are 2) increase objective focal lent and 4) increase eyepiece focal lent.

The following statements will increase a telescope's magnification: increase objective focal lent and increase eyepiece focal lent.

The image of the objective depends on the eyepiece. You have to adjust the objective's image to the eyepiece distance. It is going to magnify the image. Eyepieces are interchangeable. So you can adjust to the appropriate one depending on the distance of the observation object.
