We could separate this region into developed nations (such as north west America, eastern Asia , and wester europe) and non-developed nations (such as most region in africa, some regions in middle east and some region in eastern europe)
The consumption of food, water and energy in developed nations is clearly in abundance. If you go to any trash can in developed nations, you will see many residual food that people would throw simply because they do not want it anymore.
In non-developed nations on the other hand, most people would be desperate to obtain all of those things. Even the food that being thrown out by people in developed nation will be a luxury for them.
The correct answer is - True.
Oceanic lithosphere is lighter than the continental lithosphere, and this is because the oceanic lithosphere is thinner than the continental lithosphere. The oceanic lithosphere is softer and thinner, and in this parts the geologic activities are much more intense because the high temperature and pressure from the mantle manage to penetrate these parts easier and push magma upwards, creating volcanoes in meantime, as well as lots of earthquakes.
Answer:
Option (A)
Explanation:
In the above-given question,
Option (B) is wrong with it's usage of the modifier "how'' in the sentence. If the modifier is used in one place (how heat from the inner core flows), it should also be used in the continuing clause (how the formation and periodic reversal).
Options (C) and (D) are wrong in using the word "are" for the whole sentence as there is no need to use this word. The verb form will depend on the subject, in this case, is "the discovery that earth's inner core" which is singular in nature. Thus, the verb form will be -is and not -are.
Option (E) is wrong for it's use of the comma. If the comma is used, then the whole sentence is not a full-fledged sentence but rather a dependent clause with no resolution.
The correct answer for the given passage is option (A).
