Consider the assembly line below. The three fabrication operations run in parallel, such that each batch of 20 units only needs to go through one of the three fabrication operations After that, each batch needs to go through both assembly operations, which occur simultaneously (specifically, 10 components are made for each unit in the fabrication stage—some components are then assembled in the Assembly 1 area while others are assembled in the Assembly 2 area). The units are packaged and made ready for shipment in the final stage.
What is the throughput time per batch of this operation?
A) 88 min.
B) 8 min.
C) 40 min.
D) 34 min.
E) 33 min.

Juanita and sam attend a beach party and notice that the local beach appears to have a great deal more trash washed up on shore than it did when they were young. the water doesn't appear nearly as clear, and there seems to be less evidence of small water creatures living in the shallows. an afternoon at the local library convinces them that one major cause is the new factory nearby. after some discussion, they decide their next step should be identifying the cause of the changes identifying the problem picketing the guilty factory lobbying their elected representatives to complain about the problem talking to a local environmental group about solutions
