Question

read the paragraph, then choose the word that best completes the sentence. the age of discovery is nowhere near ending when it comes to space exploration. in 2003, scientists discovered an object about three times farther away from earth than pluto is. the new discovery is called sedna, named for an inuit goddess who created arctic sea creatures. scientists say that the name is fitting. sedna’s temperature is a bone-chilling 400 degrees f (240 degress c) below zero. sedna is ______. a atomic b grisly c explosive d distant

Explanation:

To solve this, we analyze the context. The paragraph says Sedna is an object "about three times farther away from Earth than Pluto is" and has a very low temperature. Let's analyze each option:

• Option A: "atomic" relates to atoms, which is not relevant here.
• Option B: "grisly" means horrifying or gruesome, which doesn't fit the context of a celestial object's distance or temperature.
• Option C: "explosive" relates to explosions, not relevant to Sedna's description.
• Option D: "distant" fits because Sedna is described as being far from Earth (three times farther than Pluto), so "distant" accurately describes Sedna.

Answer:

D. distant
