Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank. Any (1) _____ that revolves around a planet is a satellite. Mother Earth has a natural satellite on the moon. The Earth is circled by a lot of man-made or artificial satellites. In 1957, the Soviet Sputnik was the first to be (2) _____ into space. There are currently a number of artificial satellites launched into space by various nations. These satellites make it possible for us to talk on the phone, watch television, predict the weather, map the various surfaces of the earth, and learn more about the world in which we live. How does a satellite get started? It is typically launched into space by means of a rocket. After ascending into the thinner air layers above the earth, the satellite is released from the rocket. For a successful satellite launch, a rocket's speed is carefully calculated and controlled. Every object in space is pushed towards the Earth's centre by gravity. The inertia of motion will propel the object into space if it has its own velocity of motion. When the orbital velocity is exactly right, these two opposing forces are balanced, causing the satellite to (3) _____ towards the earth while still hovering over its surface. earth in a 24-hour period; It doesn't change when compared to a point on the surface of the earth. These orbits are typically used by satellites for communication and weather. The camera on the weather satellites takes pictures and sends them back to Earth. These are helping aid in weather forecasting. Radio receivers and amplifiers on communication satellites can (4) _____ waves back at a frequency that is different from the one the satellite received. The beaming frequencies of satellites that are 'parked' too close to one another must not interfere with one another. Television signals can be transmitted from one location to another using broadcast satellites, and scientists can (5) ______ scientific data from numerous satellites. Select the most appropriate option to fill in the blank no. 5.
Option 1: access
Option 2: entry
Option 3: approach
Option 4: ingress
Correct Answer: access
Solution : The first option is the correct choice.
Access means the ability or permission to enter, use, or retrieve something, such as information or a location, and is the appropriate choice in this context.
The meanings of the other options are as follows:
Question : D, E, and F are the midpoints of the sides BC, CA, and AB, respectively of a $\triangle ABC$. Then the ratio of the areas of $\triangle DEF$ and $\triangle ABC$ is:
Option 1: $\frac{1}{2}$
Option 2: $\frac{1}{4}$
Option 3: $\frac{1}{8}$
Option 4: $\frac{1}{16}$
Correct Answer: $\frac{1}{4}$
Solution : Given: D, E, and F are the midpoints of the sides BC, CA, and AB, respectively of a $\triangle ABC$.
$DF || BE$ and $DF = \frac{1}{2}BC$ Since the opposite sides of the quadrilateral are equal and parallel. So, BDFE is a parallelogram. Similarly, DFCE
Question : Directions: Select the option that is related to the fifth term in the same way as the second term is related to the first term and the fourth term is related to the third term. 24 : 2 :: 81 : 3 :: 375 : ?
Option 1: 15
Option 2: 5
Option 3: 9
Option 4: 7
Correct Answer: 5
Solution : Given: 24 : 2 :: 81 : 3 :: 375 : ?
Like, 24 : 2→2 + 4 = 6 (Sum of digits of the first number); 24 ÷ 6 = 4; √4 = 2 81 : 3→8 + 1 = 9 (Sum of digits
Question : Directions: Select the option figure in which the given figure is embedded. (Rotation is not allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation of the figure is not allowed, we will check where the question figure can exactly fit itself in the given option figures.
From the above, it is clear that the given question figure is embedded in the third option figure. Hence, the third
Question : If in a $\triangle$ABC as drawn in the figure, AB = AC and $\angle$ACD = 130°, then $\angle$BAC is equal to:
Option 1: 60°
Option 2: 50°
Option 3: 70°
Option 4: 80°
Correct Answer: 80°
Solution : $\angle$ACD = 130° Now, $\angle$ACD + $\angle$ACB = 180° ⇒ 130° + $\angle$ACB = 180° ⇒ $\angle$ACB = 180° – 130° = 50° Since AB = AC, ⇒ $\angle$ABC = $\angle$ACB = 50° We know that $\angle$ABC + $\angle$ACB + $\angle$BAC = 180° ⇒ 50°
Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".

Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 2
Solution : The phrase "like a mule" in part (2) is incorrect because it doesn't convey the intended meaning. Instead, it should be "because he is tall" to explain why he can be a basketball player. "Like a mule" is a simile that doesn't fit in this

Question : Comprehension:
Read the given passage and answer the questions that follow.
The sage of science, Einstein, was sitting in a depressive and pensive mood one evening. His eyes were brimming with tears. The pain was evident on his face. He peeped out of the window of his room. The sun had set a few minutes back. The sky was filled with a reddish glow. At this sunset, he felt that it was humanity that had sunk into devilish darkness and the reddish glow in the sky was the blood of humanity spilling all over the sky from earth. With tired steps, he walked back to his chair and settled down. It was the 9th of August 1945. Three days back, he had felt the same agony as if someone had torn him apart. He was deeply hurt and depressed when he heard on the radio that America had dropped an atomic bomb on the Japanese city, of Hiroshima. Today, within three days another bomb was dropped on another city, Nagasaki and lakhs of people had been killed.
He had heard that the blast released so much energy that it had paled all past destructions in comparison and death had played out a pitiable dance of destruction. The flames that broke out of the bomb were burning, melting, and exploding buildings. Scared of the heat of the bomb, people had jumped into lakes and rivers, but the water was boiling and the people too were burnt and killed. The animals in the water were already boiled to death. Animals, trees, herbs, and fragrant flowering plants were all turned into ashes. The atomic energy destruction had just not stopped there. It had entered the atmosphere there and had spread radiation that would affect people for generations to come and would also bring about destructive irreversible biological change in animals and plants.
As the news of the atomic attack reached Einstein, and he became aware of the glaring horror of the abuse of atomic energy, his distress and restlessness knew no bounds. He could not control himself and picked up his violin to turn his mind on to other things. While playing the violin, he tried to dissolve his distress in its sad notes, but couldn’t. He was burning on the embers of destruction; his heart was filled with an ocean of agony and tears just continued streaming uncontrollably out of his eyes. Night had fallen. His daughter came up and asked him to eat something as he had not taken anything for the last four days. His voice was restrained and he said, “I don’t feel like eating.”
He could not sleep that night. Lying down, he was thinking about how he had drawn the attention of the then-American President Roosevelt toward the destructive powers of an atomic bomb. He had thought that this would be used to scare Hitler and put an end to the barbarism that Hitler was up to. However, Roosevelt kept him in the dark and made false promises. Eventually, he abused Einstein’s equation of E = mc2 which resulted in destructive experiments. His actions had made science and scientists as murderers. Einstein kept on thinking for a long time. Eventually, he slipped into sleep. When he woke up at dawn, there was a new dawn in him too. The atomic threat had transformed his heart.
