This is a Must be false question.

I have a difficult time making two different diagrams about the conditions.

[ Chelas and Stelma are required to leave their respective stations immediately to pursue any prisoner who attempts to escape from their sector. Furthermore, unless they are pursuing such a prisoner, Chelas and Stelma are forbiddened to leave their stations until their replacements have arrived. ]

My thought is 1. pursue any prisoner who attempts to escape -> C and S leave their sectors

2. ~forbbidened to leave stations until their replacements have arrived -> pursue prisoner

Can you help me to make right diagrams?

Hi, this is a necessary assumption question.

The conclusion is "by using recycled glasses instead of glass made from raw materials, bottlers can lower their costs and benefit the environment at the same time."

The answer is D. "purchasing and transport costs are not so much greater for recycled glass than for raw materials that they outweigh the savings in energy costs resulting from the use of recycled glass."

I cannot understand why the answer is D.. and also I cannot get the meaning of D. The savings in energy costs are outweighed by...

please, help me!
