This is a really hard question.
It starts off really asking you whether life got better - and you think: well - it's about different groups. Some groups - like middle class workers in modern industries - propsered, and were buying new cars and gadgets and rich. Some groups - black Americans, farmers, workers in old industries - fell behind the average (despite the New Deal).
But then it asks you how far Roosevelt was responsible for this. I know it's aboutthe new Deal, but in asking this, it rather assumes that you have answered the first part 'Yes'.
One possible way to approach this, at GCSE level, would be to merge the two together and answer it all at once as though it were simply a 'how successful was the New Deal' question, like this:
QUOTE
Section 1: FOR
1. Restored confidence (fireside chats).
2. Ended banking crisis.
3. The ‘Alphabet Agencies’ combated unemployment and homelessness, created jobs, supported business and farming.
4. TVA.
5. Social benefits of the Second New Deal.
Section 2: AGAINST
1. Limited help to Black people and farmers.
2. Unemployment was reduced, but stayed high.
3. The attempt to reduce funding in 1937 failed.
4. America stayed on the Gold Standard, which continued to damage exports.
5. Interest rates stayed high, which held back industry.
6. Needed World War II and Lend-Lease to get the economy going again
7. What about all those 'other factors which Roosevelt didn't affect - inventions, science, 'new industries'.
Jut make sure all the way through you kee mentioning how these made life better or worse, and how much they were or were not down to Roosevelt.
