Disclaimer- this is all assuming that "semi monthly" means twice a month. if it doesn't, ignore this answer
A- if semi monthly is half a month, then 4 times 2 is 8, and 8 times 12 is 96,000. 
B- If there are 4 weeks in a month and 4000$ accounts for half of that pay, then the weekly pay is 2000, making the bi-weekly pay 1000.
C- The monthly pay is 8,000$ because 4,000 x 2 is 8,000
D- The weekly pay is 2,000$ because the monthly pay is 8,000$ and there are 4 weeks in a month
E- I do not know the hours at this job and therefore cannot answer this
