Question

laboratory layout
stations a, b, and c are fume hoods.
stations d, e, f, g, and h are gas chromatographs.
a science teacher has a 2 - hour class period with no extra time for preparation before the class. the teacher may only use stations a and c. the teacher chooses experiment 6 for the class to perform. is this choice correct given the teachers needs, and why?
a yes, because experiment 6 can be completed in under 2 hours.
b yes, because experiment 6 needs a station with a fume hood.
c no, because experiment 6 needs a station with a fume hood.
d no, because experiment 6 requires 1 hour of additional preparation time.

Explanation:

The teacher has a 2 - hour class with no prep time and can only use Stations A and C which are fume hoods. There is no information indicating Experiment 6 can be completed in under 2 hours or its time requirements. But if it requires a fume hood, Stations A and C meet that need. Without any mention of prep - time requirements for Experiment 6, we assume the key factor is the station type. Since the teacher can use fume - hood stations (A and C) and if Experiment 6 needs a fume hood, the choice is correct.

Answer:

B. Yes, because Experiment 6 needs a station with a fume hood.
