I wonder if they mean that the perceived location of the quasar in the sky will change, or if the position will physically change? The gravitational law says the force exerted on one body by another is proportional to the product of their masses and inversely proportional to the square of the distance between them. Jupiter has a relatively small mass compared to stars, and probably to quasars. I would expect Jupiter to move more than the quasars will. Of course, Jupiter may move more due to the influence of its moons, the other planets, and the sun than to quasars that are light years away. Do you think these students are smart enough to figure all of this out?

None of these bodies are stationary - everything is in motion. Jupiter about the sun, the solar system about the center of the galaxy, the quasars in motion about some unseen point. The perceived location of the quasars today is not the actual physical position of them right now - we are seeing light from them where they were however many light years ago.

Since the quasars are so many light years away from Jupiter, it will take at least that many years (if speed of gravity equals the speed of light) for any perceptible change in the motion of Jupiter or the quasars to be affected by each other. If the speed of gravity is less than the speed of light, it will take longer for them (however many light years plus the difference in the speeds) to find out. I think they will be a lot older when they figure this out!

Methinks this is either a hoax or a simplicity of thought by the university professors and/or students.

I think really poorly written

Jupiter getting really close to a Quasar, close enough for its gravity to move the quasar even a bit, I think not.

Perhaps, Jupiter will be really close to the line between the earth and the Quasar, and bend the light coming from the quasar on its way to earth.

Yes, and much more.
