In the context of science, how would you classify the following statement? Dinosaurs become
extinct because a large asteroid collided with Earth. correct answers B. Hypothesis
Pluto was discovered in 1930, becoming the 9th planet in the solar system. As telescopes
improved, other Sun-orbiting objects were discovered. Some of those were even larger than
Pluto. By 2005, it was becoming apparent that many more objects would soon be discovered and
that the number of planets in the Solar System could swell to as many as 50. After much debate,
scientists in the International Astronomical Union (IAU) concluded that Pluto and the other
similar celestial bodies orbiting the Sun should be classified as "dwarf" planets. Since a "planet"
must clear the space surrounding its orbit, our Solar system now has 8 planets. correct answers
D. Science is limited by *technology.*
Pluto still exists, so how do you explain that we now officially only have *8* planets in our solar
system? correct answers A. Scientific explanations are *ten*tative.
Why are scientists expected to publish the data they use to make discoveries? correct answers B.
