Answer: (E.) III and IV
Explanation: Explaining the answers, the question shows us an already existing demographic challenge, as the population tends to live longer and have less desire to procreate. To solve this problem the government needs to;
a) carry out paid maternity leave : This would motivate the population, especially the female population to want to give birth.
b) Building more schools :
Building more schools would ensure education is free for the young upcoming population, therefore encouraging the population to procreate more.
Answer: Kind of like a Base Camp . . .
Explanation: Think about it this way, you are in a large group going on a long trip, you need to stop say for about 2-3 weeks(Maybe for people to treat injuries, or recover from them), and you set up a place to stay just for a little bit.
Hope this helps!
Answer: b. Clear-cutting
Explanation: Clear cutting is a cheap and effective way of harvesting trees or timbers, this methods helps the forest operators to get the best out of a forest at a very reduced cost.
Clear-cutting is bad because removing the whole tree from an area destroys outrightly the natural habitat of most widelife, and it will also lead to the destruction of the eco-system that relies on the forest.
Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.
