Explanation:

Question 35:

Trench warfare developed because defensive weapons made open attacks suicidal. Machine guns (option d) could mow down advancing troops at long range, forcing armies to dig trenches for protection. Tanks (a) were developed later to break trench stalemates, flamethrowers (c) were a close-range weapon, and poison gas (b) was an offensive tool but not the core driver of trench warfare's creation.

Question 36:

During WWI, the U.S. military was strictly segregated. African American soldiers were mostly assigned to non-combat support roles, and their units were segregated by race. They were not integrated (d), rarely allowed to become officers on equal footing with whites (b), and only some regiments served under French (not British) command (a).

Question 37:

In Schenck v. United States, the Supreme Court established the "clear and present danger" test. It ruled that free speech can be restricted if it creates a clear, immediate risk of harm; Schenck's anti-draft leaflets were seen as threatening the war effort during WWI.
