Question

use what you learned from reading the science articles to answer the following questions.
1 this question has two parts. first, answer part a. then answer part b.
part a
which statement best describes a major difference between “exploring mars” and “living on mars”?
a “exploring mars” describes inspiring reasons for human exploration of mars, while “living on mars” argues that it would be too difficult for humans to live there.
b “exploring mars” tells about problems nasa has faced in sending spacecraft to mars and solutions to these problems, while “living on mars” presents problems and possible solutions to living on mars.
c “exploring mars” tells about events in the history of the exploration of mars, while “living on mars” presents problems and possible solutions to living on mars.
d “exploring mars” describes causes and effects of space exploration, while “living on mars” presents expert opinions about why humans should try to build a settlement on mars.

part b
choose one sentence from each article that supports the answer in part a.
a “have you ever thought about exploring mars?” (\exploring mars\)
b “in november 1964, the u.s. national aeronautics and space administration (nasa) launched mariner 4.” (\exploring mars\)
c “curiosity is gathering evidence from rocks and soil.” (\exploring mars\)
d “do you think it is possible to live on mars?” (\living on mars\)
e “another problem is that mars is very cold, windy, and dusty.” (\living on mars\)
f “maybe one day you’ll be making the trip.” (\living on mars\)

Explanation:

For Part A: Option C correctly identifies the core difference: "Exploring Mars" focuses on the historical timeline of Mars exploration, while "Living on Mars" addresses the challenges and potential fixes for human habitation there.
For Part B: Sentence B from "Exploring Mars" provides a specific historical event (1964 Mariner 4 launch) supporting the chronological focus of the article. Sentence E from "Living on Mars" highlights a key problem of living on Mars, supporting the problem-solution focus of that text.

Answer:

Part A:

C. "Exploring Mars" tells about events in the history of the exploration of Mars, while "Living on Mars" presents problems and possible solutions to living on Mars.

Part B:

B. "In November 1964, the U.S. National Aeronautics and Space Administration (NASA) launched Mariner 4." ("Exploring Mars")
E. "Another problem is that Mars is very cold, windy, and dusty." ("Living on Mars")
