Writing Homework Help

I’m stuck on a English question and need an explanation.

1- What three social science methods are discussed in these examples? (You may simply name or describe these.)

2- When faced with something like the development of reusable spaceship parts to more cheaply deliver satellites and space station employees to orbit (like SpaceX), what kinds of social science research methods might guide corporations? (You might start by considering what kinds of developmental decisions companies like SpaceX must make, and then what kind of information would help them make the best decisions.) (A few sentences will do here–50-100 words.)
