nope
jimthompson5910 (jim_thompson5910):
for example, step 1 is the first step, so there is no way this is the conclusion (since that's the last line)
So we can cross off choice C
jimthompson5910 (jim_thompson5910):
agreed or no?
OpenStudy (dj3strella):
yes
@jim_thompson5910
jimthompson5910 (jim_thompson5910):
What is step 1. Go ahead and write that out.

is step 1. AC=BD?
jimthompson5910 (jim_thompson5910):
yes
jimthompson5910 (jim_thompson5910):
where else is that equation mentioned or listed?
OpenStudy (dj3strella):
Step #5
jimthompson5910 (jim_thompson5910):
step 5's equation is different from step 1

AC = BD is listed somewhere else, but not in step 5
OpenStudy (dj3strella):
oh my bad i just nocited that
jimthompson5910 (jim_thompson5910):
where is AC = BD listed (other than step 1)?
OpenStudy (dj3strella):

don't look in the table
jimthompson5910 (jim_thompson5910):
look above the table
jimthompson5910 (jim_thompson5910):
where is AC = BD listed (other than step 1)?
OpenStudy (dj3strella):
umm If AC=BD, then AB=CD
jimthompson5910 (jim_thompson5910):
yes, notice how it says "If AC = BD"
the key here is that IF

it all hinges on that
jimthompson5910 (jim_thompson5910):
the "if AC = BD" is known as a premise. It is a building block of an argument
jimthompson5910 (jim_thompson5910):
The assumption is that the premise is true which leads to the conclusion. So that's why the answer is choice A) true premises
OpenStudy (dj3strella):
because its true. If AC= BD is the first step
jimthompson5910 (jim_thompson5910):
because AC = BD is assumed to be true, it leads to the rest of the steps eventually leading to the conclusion

jimthompson5910 (jim_thompson5910):
if AC = BD isn't true, then the whole argument doesn't work
OpenStudy (dj3strella):
umm then idk what it would be
OpenStudy (dj3strella):
can you tell I don't understand this lol
OpenStudy (dj3strella):
@jim_thompson5910
jimthompson5910 (jim_thompson5910):
I just told you the answer
