Final answer:
The given statement 'Immediately after "Lady Be Good," the two brothers always collaborated' is false, as many contributed significantly to the war effort. The claims about both Americans and British giving up Mississippi claims and the success of Jefferson's economic pressure tactics are both false; the Americans gained territory and Jefferson's efforts were unsuccessful. So, the correct answer is b. False.
Step-by-step explanation:
The original question about the collaboration of two brothers on 'Lady Be Good' is not directly connected to the provided reference information and seems to refer to the works of George and Ira Gershwin.
Thus, no accurate answer can be given on that particular collaboration in this context.
However, I can address the historical statements provided in the exercises:
Exercise 8.3.2: The statement that 'many women found themselves incapable of handling the burdens of war when their husbands and fathers went off to fight' is false.
Many women, in fact, took on various roles during wartime, stepping into jobs left vacant by men and supporting the war effort in numerous ways.
Exercise 8.4.2 and 2: The statement that 'Both the Americans and the British gave up claims to the Mississippi for the sake of peace' is false.
In the Treaty of Paris 1783, which ended the American Revolutionary War, Britain acknowledged American independence and ceded territory east of the Mississippi River to the United States, but did not give up its Canadian territories west of the Mississippi.
Exercise 11.1.3: The statement 'Jefferson's efforts to use economic pressure to solve the situation with Britain and France were successful' is false. The Embargo Act of 1807, which Jefferson advocated for, was largely unsuccessful and caused significant economic hardship in the U.S. instead.
Thus, the correct answer is b. False.
Question: After their joint work on "Lady Be Good," did the two brothers consistently collaborate on subsequent projects?
a. True
b. False
