"[S]ome recent university graduates consider work environment an important factor in choosing a job"
Recent grads - some - Work environment important Work environment important - some - Recent grads
"[A]ll [recent university graduates] consider salary an important factor"
Recent grads --> Salary important Salary not important --> Not recent grads
"[T]he only workers who consider stress level an important factor in choosing a job are a few veteran employees." In other words, the only workers who consider stress level important are not recent grads.
Remember "the only" introduces a sufficient condition.
Stress important --> Not recent grads Recent grads --> Stress not important
"[E]very recent university graduate considers vacation policy an important factor."
Recent grads --> Vacation important Vacation not important --> Not recent grads
So, what can we conclude? Remember that we can combine an S&N statement with a quantifiers statement if the sufficient condition is common and the arrow points away from the quantifier.
Work environment important - some - Recent grads --> Salary important
Work environment important - some - Recent grads --> Stress not important
Work environment important - some - Recent grads --> Vacation important
Therefore, we can conclude that:
1) Some people who consider work environment an important factor also consider salary to be an important factor.
2) Some people who consider work environment an important factor do not consider stress to be an important factor.
3) Some people who consider work environment an important factor also consider vacation to be an important factor.
Notice that our third conclusion above is restated by answer choice (B), making it our correct answer.
Hope this helps! Please let us know if you have any further questions.
