How many pancreases from beef animals would it take to provide
the insulin required by one
human patient for one year?
A. 15
B. 19
C. 26
D. 32

Without other information, the number of animals maybe between 19-73 depending on age and pancreas size. Of the options presented, the nearest answer is D.32

Explanation: Assumptions

2yo cow with pancreas 400g

insulin content ~5 IU (175ug)

Daily insulin requirement 0.5-1 IU —> 187-365 IU p.a.

beef animals required 37-73 cows

using 6 mo calves, the insulin content is ~10IU, so requiring 19-37 calves

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
