The nearly circular orbits of planets in our solar system led scientists to expect that planets around other stars would also reside in circular orbits. However, most known extrasolar planets reside in highly elongated, not circular, orbits. Why? The best clue comes from comets in our solar system. Comets formed in circular orbits but were gravitationally flung into their present-day elliptical orbits when they ventured too close to planets. Astronomers suspect that pairs of planets also engage in this slingshot activity, leaving them in disturbed, elliptical orbits. If two planets form in close orbits, one will be scattered inward (toward its star), the other outward. They will likely then travel close enough to neighboring planets to disturb their orbits also.
1. According to the passage, which of the following factors help account for the elliptical shape of the orbits of extrasolar planets?
I. The planets’ formation in close proximity to other planets
II. The gravitational influence of planets whose original orbits have been disturbed
III. The gravitational influence of comets
A. I only
B. I and II only
C. I and III only
D. II and III only
E. I, II, and III

Difficulty Level: 700
Explanation
Relevant part of the passage:
Astronomers suspect that pairs of planets also engage in this slingshot activity, leaving them in disturbed, elliptical orbits. If two planets form in close orbits, one will be scattered inward (toward its star), the other outward. They will likely then travel close enough to neighboring planets to disturb their orbits also.
Choice I: deflect away from each other
If two planets form in close orbits, one will be scattered inward (toward its star), the other outward
Choice II: change the shape of each other's orbit
Leaving them in disturbed, elliptical orbits
Choice III: affect the orbits of any neighboring planets
They will likely then travel close enough to neighboring planets to disturb their orbits also

Reference from Passage. Lines 9-12 mention that elliptical shaped orbits resulted from 'slingshot activity' ie, gravitationally flung into such orbits (proof for prompt I). Also, the elliptical orbits for certain planets result consequent to certain planets travelling close to the planets whose original orbits have been disturbed. (proof for prompt II)
