Question : Comprehension:
Read the given passage and answer the questions that follow.
As the Sun inches closer to its peak activity in its solar cycle, an explosion has been picked up behind the northeastern limb of the star in our solar system. Solar observatories saw bits and pieces of the explosion, which remain obscured in view from Earth's orbit.
The explosion was spotted on 31 July at around 2309 UT and Earth-orbiting satellites registered a long-lasting C9.3-class solar flare. "The intensity is probably an underestimate because it was partially eclipsed by the edge of the sun. Nasa's Solar Dynamics Observatory (SDO) saw hot debris flying away from the blast site," space weather, which tracks the solar activity, reported.
While the explosion was powerful, experts have predicted that Earth is not in the line of fire from the Sun. Scientists are expected to get a view of the active region later this week as it comes to sight. Earth is not in the line of fire. The explosion is significant because it may herald an active region set to emerge over the sun's northeastern limb later this week. A new sunspot group could bring an end to weeks of relative quiet," Space Weather said in its report.
Select the most appropriate synonym of the given word from the passage.
Partially
Option 1: Supportively
Option 2: Partly
Option 3: Frankly
Option 4: Completely
Correct Answer: Partly
Solution : The correct choice is the second option.
Partially means something that is not complete. Partly means something that is completed to some degree but not completely, making it the appropriate synonym for "partially".
The meanings of the other options are as follows:
Debris
Option 1: Detritus
Option 2: Rays
Option 3: Specks
Option 4: Liquid
Correct Answer: Detritus
Solution : The correct choice is the first option.
Debris means the remains of something that is broken or destroyed. Detritus means waste material left, especially after a particular event, making it a synonym for "debris".
Question : The value of $\frac{4 \tan ^2 30^{\circ}+\sin ^2 30^{\circ} \cos ^2 45^{\circ}+\sec ^2 48^{\circ}-\cot ^2 42^{\circ}}{\cos 37^{\circ} \sin 53^{\circ}+\sin 37^{\circ} \cos 53^{\circ}+\tan 18^{\circ} \tan 72^{\circ}}$ is:
Option 1: $\frac{35}{48}$
Option 2: $\frac{59}{48}$
Option 3: $\frac{49}{24}$
Option 4: $\frac{35}{24}$
Correct Answer: $\frac{59}{48}$
Solution : Given: $\frac{4 \tan ^2 30^{\circ}+\sin ^2 30^{\circ} \cos ^2 45^{\circ}+\sec ^2 48^{\circ}-\cot ^2 42^{\circ}}{\cos 37^{\circ} \sin 53^{\circ}+\sin 37^{\circ} \cos 53^{\circ}+\tan 18^{\circ} \tan 72^{\circ}}$ We know that $\tan 30^{\circ} = \frac{1}{\sqrt{3}}$ $\sin 30^{\circ} = \frac{1}{2}$ $\cos 45^{\circ} = \frac{1}{\sqrt{2}}$ $\cos 37^{\circ} = \cos (90^{\circ} - 53^{\circ})
Question : The short-run marginal cost curve is __ shaped.
Option 1: U
Option 2: V
Option 3: X
Option 4: W
Correct Answer: U
Solution : The correct answer is U.
In the short term, the law of variable proportions has the marginal cost curve to be U-shaped. The Marginal cost (MC) curve, by law, first slopes downward until it reaches its lowest point, at which point it begins to

Peak
Option 1: Glance
Option 2: Point
Option 3: Bottom
Option 4: Zenith
Correct Answer: Zenith
Solution : The fourth option is correct.
A peak is the highest point of something.
Zenith refers to the highest point reached by a celestial body. Both of these words signify the highest point or culmination of something, making them synonymous.
The meanings of the other options
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: 3
Solution : The error lies in the third part of the sentence.
Explanation: The verb tense in third part should be consistent with the past tense established in the first part of the sentence ("They had often heard"). Therefore, it should be "they had to travel on"
