b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point, so the egg is boiling in water at a lower temperature.
Explanation:
The best answer from the given choices is that, at higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point,
so the egg is boiling in water at a lower temperature.
- Boiling point is simply the pressure at which the vapor pressure of a liquid is equal to the atmospheric pressure.
- At higher elevations, the atmospheric pressure is low and it would require little heat to boil water and turn it into vapor.
- To hard boil an egg, we need elevated temperature.
- But since water to use hard boiling has an unusually low temperature, it becomes more difficult since much of the water turns into vapor.
- This is why at higher elevations, it takes a longer time to hard boil eggs.

Explanation:
South Africa's location makes it a key spot for renewable energy in the forms of wind, hydroelectric and solar, as it is on the peninsula of the continent it has access to many of these rich resources. There is also a great deal of industry in South Africa, particularly in the mining of metals, as one of the country's largest exports. This extraction uses huge amounts of energy in the process and most of this equipment used in the extraction pumps toxic gases and chemicals into the atmosphere, if SA uses more renewable energy sources, the levels of pollution will decrease.
