Explanation:

For Part A:

The titles "Exploring Mars" and "Living on Mars" indicate their core focuses. "Exploring Mars" centers on missions to study Mars, so it would detail mission purposes. "Living on Mars" addresses the practicality of human habitation, meaning it would cover overcoming related challenges. Other options are inconsistent with logical article focus: A introduces an unstated cost argument, C misframes "Exploring Mars" as problem-focused and "Living on Mars" as emotional, D reverses the expected content of each article.

For Part B:

To support the Part A answer, we need a sentence showing "Exploring Mars" covers mission progress/learnings (option C highlights mission-driven knowledge gain over 50 years) and a sentence showing "Living on Mars" addresses habitation challenges (option E points out a supply challenge of living on Mars).

For Question 3:

The suffix "-ible" is a common adjective-forming affix that conveys the meaning of being capable of or fit for the action related to the root word. In "flexible," it means the suit is able to be flexed.

Answer:

Part A:

B. "Exploring Mars" describes the purposes of each mission to Mars, while "Living on Mars" describes ways to overcome challenges to living there.

C. "Over the past 50 years, scientists have learned a great deal about Mars." ("Exploring Mars")
