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 hypocentre 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: According to the passage, what is the location of the start of the earthquake directly above it on the surface of the earth is called?
Option 1: Epicentre
Option 2: Centroid
Option 3: Hypocenter
Option 4: Orthocentre
Correct Answer: Epicentre
Solution : The correct choice is the first option.
According to the first paragraph of the passage, epicentre is the location above the earth's surface where the earthquake starts, thus making it the appropriate choice.
Therefore, the correct answer is epicentre.
Question : Directions: Which two signs and two numbers should be interchanged in the following equation to make it correct? 23 × 13 – 195 ÷ 17 + 40 = 366
Option 1: 23 and 40; × and –
Option 2: 23 and 17; × and ÷
Option 3: 13 and 17; × and +
Option 4: 13 and 17; + and –
Correct Answer: 13 and 17; + and –
Solution : Given: 23 × 13 – 195 ÷ 17 + 40 = 366
Let's check each option – First Option: 23 and 40; × and – On interchanging the mathematical signs and numbers, we get – 40 – 13 × 195 ÷ 17 + 23 = 366 On solving the L.H.S. of the equation – = 40 – 13 × 195 ÷ 17 + 23 = 40 – 13 × 11.47 + 23 = 40 – 149.11 + 23 = –86.11 ≠ 366 Second Option: 23 and 17; × and ÷ On interchanging the mathematical signs and numbers, we get – 17 ÷ 13 – 195 × 23 + 40 = 366 On solving the L.H.S. of the equation – = 17 ÷ 13 – 195 × 23 + 40 = 1.31 – 195 × 23 + 40 = 1.31 – 4485 + 40 = –4443.69 ≠ 366 Third Option: 13 and 17; × and + On interchanging the mathematical signs and numbers, we get – 23 + 17 – 195 ÷ 13 × 40 = 366 On solving the L.H.S. of the equation – = 23 + 17 – 195 ÷ 13 × 40 = 23 + 17 – 15 × 40 = 23 + 17 – 600 = –560 ≠ 366 Fourth Option: 13 and 17; + and - On interchanging the mathematical signs and numbers, we get – 23 × 17 + 195 ÷ 13 – 40 = 366 On solving the L.H.S. of the equation – = 23 × 17 + 195 ÷ 13 – 40 = 23 × 17 + 15 – 40 = 391 + 15 – 40 = 366
So, only the fourth option satisfies the equation. Hence, the fourth option is correct.
