Ответ:
Choice A
4-3=2 is false
6*3=9 is false
both parts are false, so overall the entire disjunction is false
Choice B
5*6=30 is true
3+4=7 is true
Neither part is false, so overall the entire thing is true
Choice C
8+3=11 is true
5*4=23 is false
While second piece is false, the overall disjunction is true. The first part (true) makes the whole thing true.
Choice D
7+6=13 is true
5*2=10 is true
Neither part is false, so overall the entire thing is true
In summary, we have
A. False
B. True
C. True
D. True
Making choice A the only answer that is false. So choice A is the final answer
