Increasing demand for flat-screen TVs, according to estimates, could have a greater impact on global warming than the world's largest coal-fired power plants. Flat screen manufacturers use a greenhouse gas known as nitrogen trifluroide, and as these displays are becoming more and more popular, annual gas production has grown to about four thousand tons. Nitrogen trifluroid is the most dangerous global warming engine, for comparison, this gas is 17,000 times stronger than carbon dioxide.

About WHY schools should educate students how to manage money and how to do taxes???
---
I think schools SHOULD teach students how to do their taxes because it's an aspect of adulthood they are almost otherwise unprepared for completely. Most school's curriculum is based on 4 core classes and various electives, but life is more than those 4 classes. Taxes, money managements, and management of other areas of life would be tremendously useful and I think there would be an immeasurable difference made in the lives of the students. They would be more prepared for financial obstacles they may face, and they'd more than likely be more successful in their transition in adolescence.
A parallel sentence mentions the same grammatical expression twice. I would go with "D". 'Passed' and 'Demonstrated' are both past tense words that express the same past tense grammatical idea.
If you have more questions, feel free to ask me.
