Question

review the third and fourth paragraphs.
3 most comet dust in meteor showers bums up in the atmosphere before reaching the ground; some dust is captured by high-altitude aircraft and analyzed in nasa laboratories. chunks of rock and metal from asteroids and other planetary bodies that survive their journey through the atmosphere and fall to the ground are called meteorites. scientists estimate that forty- four tonnes (forty-four thousand kilograms) of meteorites fall to earth each day. most of these meteorites are pebble- to fist-sized, but some are larger than buildings. early earth experienced many large meteorite impacts that caused extensive destruction. a very large asteroid impact sixty-five million years ago, which created the three-hundred-kilometer-wide chicxulub crater on the yucatan peninsula, is thought to have contributed to the extinction of about seventy-five percent of marine and land animals on earth at the time,
how do the third and fourth paragraphs work together?
they both present examples of the same phenomenon.
they both emphasize how dangerous meteorites can be.
they both show that meteorites are a thing of the past.
they both emphasize how large meteorites tend to be.

Explanation:

The third paragraph talks about meteorites in general (their size range, daily fall amount) and the fourth paragraph gives a specific example (the large asteroid impact that contributed to mass - extinction). Both are about meteor - related phenomena. The first option is correct as they are examples of meteor - related events (meteorites falling and a large asteroid impact which is a more extreme form of meteor - like event). The second option is wrong because the third paragraph doesn't emphasize danger (just facts about meteorites). The third option is wrong as meteorites still fall today. The fourth option is wrong as the third paragraph mentions most are pebble - to fist - sized.

Answer:

They both present examples of the same phenomenon.
