There's a subtle point involved here that I'll try to explain, and
I hope you catch my explanation:
A real scientist does NOT "use evidence to support his theory".
That would mean that he dreamed up his theory, then he went
around observing the world and nature, and he wrote down and
took pictures of things he saw that supported his theory, and he
ignored anything that didn't support it. This is exactly how science
does NOT work. Anybody who operates that way is laughed out
of science and you never hear about him again.
The way science works is exactly the opposite: The curious
investigator observes the world and the things around him. He
sees how things actually work. That's the 'evidence'. Eventually
he comes to the point where he's ready to build a theory of WHY
or HOW things work the way they actually do.
The theory is built to explain the evidence. The evidence is not
used to support a theory. And after the theory is offered, the next
step is to test the theory and see if it's worth anything.
Wegener observed that m<span>ountain chains are continuous across
continents, and he learned that similar fossils have been found
on different continents. When he saw these and other facts, he
eventually offered the theory of continental drift, to EXPLAIN the
evidence.
I only see 5 points. Where are the other 19 ?

Answer:
I think it may be C but I don't know I would search it up first.
Answer: D
Explanation:
By 2100 Global warming would have more than double as the release of chlorofluorocarbons into the atmosphere does not seem to abase. The industrial zone of Pittsburgh, US contributes a lot to the increase in the atmospheric temperatures of the surrounding areas. The continually high demand for wood charcoal by pharmaceutical companies, households, and food vendors in developing countries would mean more deforestation which consequently expose the earth's crust to high insolatoon from the solar system.
However, the replacement of natural landscape by human landscape is on the rise. In the UAE, Dubai alone has u number of construction projects, from skyscrappers to artificial islands. More trees would be removed to make these construction projects possible. The consequent effect of all these cannot be anything other than more warming of the globe.
