It began with the Mercury program which used a single-passenger spacecraft.
The correct answer here is that lowers the activation energy of chemical reactions - A.
By doing this, it essentially creates an environment where a chemical reaction can happen faster because it doesn't need as much energy to actually take place - for this reason it also happens more often as a lower energy treshold is usually reached faster than a higher one.
Writing the terms down alot or just reading and reading.
