Summary
Vanessa believes that all computer code must be written by two programmers who collaborate at the same work station.
Vanessa’s belief is based on her assertion that collaboration prevents programmers from writing code that only they can understand.
Jo believes that the most productive programmers must be allowed to work by themselves.
Jo’s belief is based on two assertions: that the best programmers keep most programming projects afloat through their prolificness, and that these most productive programmers generally work better solo.
Notable Valid Inferences
The correct answer will describe an assignment that violates either Jo’s principle, Vanessa’s principle, or both principles. To violate Jo’s principle, the right answer would have to describe an assignment in which the most productive programmer on a team is forced to work collaboratively. To violate Vanessa’s principle, the right answer would have to describe an assignment wherein computer code is produced by someone other than a pair of programmers working at the same work station.

Consistent with both principles. Because Olga and Kensuke are assigned to work together at a single workstation, the assignment satisfies Vanessa’s principle. Because they’re not the most productive programmers, Jo’s principle doesn’t mandate that they be permitted to work solo.

Consistent with both principles. Because John and the new programmer are assigned to work together at a single workstation, the assignment satisfies Vanessa’s principle. Because they’re not the most productive programmers, Jo’s principle doesn’t apply.

Consistent with both principles. Because Chris and Jennifer are assigned to work together at a single station, the assignment satisfies Vanessa’s principle. Because they’re not the most productive programmers, Jo’s principle doesn’t mandate that they be permitted to work solo.

Inconsistent with Jo’s principle. Because Yolanda is the most productive programmer on the team, any assignment that is consistent with Jo’s principle must allow her to work alone.
