Please help me diagram this

Can you please help me diagram this so I know why (E) if the correct answer. I answer E however, I'm not sure if I diagrammed this correctly in the first place and feel like me answering (E) was a fluke. I diagrammed the conditional statements as follows: E==>BLSUW Not BLSUW ==> Not E HASIR==> Not BLSUW BLSUW ==>Not HASIR

In this question is it asking us to find the conclusion and therefore the conclusion is HASIR ==> Not E. Therefore the chain is as follows:

P: E==>BLSUW
Not BLSUW ==> Not E
P: HASIR==> Not BLSUW
BLSUW ==> Not HASIR
C: HASIR ==> Not E

Hi @Shirnel,

Happy to help!

You diagrammed these statements correctly! Great job!

To get to answer choice (E), you use the transitive property (as you have above) to conclude that:

HASIR - > Not BLSUW - > Not E
HASIR - > Not E

This is a direct restatement of answer choice (E), making it the correct answer.

Keep up the good work! Please let us know if you have any further questions.
