Comet A has the largest diameter at 11.3km and the longest orbit time at 82.3 years. This suggests a direct relationship. Comet B has the shortest diameter of 5.2km and the shortest orbit time at 47.8 years. This also suggests a direct relationship and this trend can be seen in the other two comets. The correct answer is the larger the diameter, the longer the orbit time.

Researchers have discovered a new planet, Planet Z. This planet is orbited by several comets, A, B, C and D. Researchers have calculated the time it takes each comet to orbit Planet Z, the closest the comet gets to Planet Z and the diameter of the comet.Another comet that orbits Planet Z was found and the comet has a diameter of 4.6km. Which of the following would be the best estimate of orbit time around Planet Z in Earth years?

Directions:Read the passage and choose the best answer to each question.PassageThe ninth planet of our solar system, Pluto, was discovered in 1930. It is the smallest planet in the solar system, with a surface area more than 300 times smaller than Earth’s. Recently, Pluto’s categorization as a planet has been debated. Two scientists discuss whether Pluto is a planet or another celestial object.Scientist 1Pluto is most certainly a planet. Some astronomers have suggested that Pluto be stripped of its planetary status, arguing that it is more accurately categorized as an asteroid or comet. However, with a 1,413 mile diameter, Pluto is almost 1,000 times bigger than an average comet, and it does not have a tail of dust and gas as comets do. A planet can be described as a non-moon, sun-orbiting object that does not generate nuclear fusion and is large enough to be pulled into a spherical shape by its own gravity. Strictly by deﬁnition alone, Pluto is a planet. Pluto is clearly not a moon, as it does not orbit another planet. Although Pluto’s orbital path is irregular as compared with the other planets of the solar system, it undisputedly orbits the sun. Pluto does not generate heat by nuclear ﬁssion, distinguishing it from a star. It is large enough to be pulled into a spherical shape by its own gravitational force, distinguishing it from either a comet or an asteroid.Scientist 2There are many facts about Pluto suggesting that it is actually not a planet but a member of the Kuiper Belt, a group of sizable comets that orbit the sun beyond Neptune. First, Pluto is composed of icy material, as are the comets in the Kuiper Belt, while the other planets of the solar system fall into one of two categories: rocky or gaseous. The four inner planets, Mercury, Venus, Earth, and Mars are rocky planets; Jupiter, Saturn, Uranus, and Neptune are gaseous. Pluto is neither rocky nor gaseous but has an icy composition. In addition, Pluto is much too small to be a planet. It is less than half the diameter of the next smallest planet, Mercury.The Earth’s moon is even larger than Pluto. Finally, the eccentricity of Pluto’s orbit indicates that it is not a planet.Pluto is generally considered the ninth planet, but for twenty years of its 249 year orbit, it is actually closer to the sun than is Neptune, making it the eighth planet during that period of time. This irregular orbit is shared by over seventy Kuiper Belt comets.Q. Which of the following phrases best describes the major point of difference between the two scientists’ viewpoints?
