Question : Comprehension:
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth's surface where the earthquake starts is called the hypocenter and the location directly above it on the surface of the earth is called the epicentre.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until a larger earthquake happens. The largest main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the main shock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!
The Earth has four major layers: the inner core, outer core, mantle, and crust. The crust and the top of the mantle make up a thin skin on the surface of our planet.
But this skin is not all in one piece; it is made up of many pieces, like a puzzle covering the surface of the earth. Not only that, but these puzzle pieces keep slowly moving around, sliding past one another, and bumping into each other. We call these puzzle pieces tectonic plates, and the edges of the plates are called plate boundaries. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults, and there is an earthquake.
Question:
On the basis of the passage, fill in the blanks in the following sentence.
The plate boundaries are made up of many ______.
Option 1: crusts
Option 2: faults
Option 3: spaces
Option 4: cores
Correct Answer: faults
Solution : The correct choice is the second option.
Faults is the appropriate choice to fill the blank with, as it is stated in the last paragraph that the boundaries of the plate are made up of faults, and most of the earthquakes occur on those faults.
Therefore, the complete sentence is: The plate boundaries are made up of many faults.

Question : Comprehension: An endangered species is a type of organism that is threatened by extinction. Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago. The hot, dry climate of the Cretaceous period changed very quickly, most likely because of an asteroid striking the Earth. The impact of the asteroid forced debris into the atmosphere, reducing the amount of heat and light that reached Earth's surface. The dinosaurs were unable to adapt to this new, cooler habitat. Dinosaurs became endangered, then extinct. Human activity can also contribute to the loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms. This can happen in several different ways.
Development can directly eliminate habitat and native species. In the Amazon rainforest of South America, developers have cleared hundreds of thousands of acres. To "clear" a piece of land is to remove all trees and vegetation from it. The Amazon rainforest is cleared for cattle ranches, logging, and urban use. Development can also endanger species indirectly. Some species, such as fig trees in the rainforest, may provide habitat for other species. As trees are destroyed, species that depend on that tree habitat may also become endangered. Tree crowns provide habitat in the canopy, or top layer, of a rainforest. Plants such as vines, fungi such as mushrooms, and insects such as butterflies live in the rainforest canopy. So do hundreds of species of tropical birds and mammals, such as monkeys. As trees are cut down, this habitat is lost. Species have less room to live and reproduce.
Based on the passage above, choose the correct option for the following question.
Question
