Question : The part of the eye having the larger refractive index is:
Option 1: cornea
Option 2: aqueous humor
Option 3: lens
Option 4: vitreous humor
Correct Answer: lens
Solution : The correct option is the lens.
Refractive Index is defined as the ratio of the speed of light in a vacuum (or air) to the speed of light in the medium. The refractive indices of the cornea, aqueous humor, lens and vitreous humor are 1.376, 1.336,1.413, and 1.336 respectively. The lens bends light rays to form a clear image on the retina. As the lens is elastic, it can change shape, getting fatter to focus on close objects and thinner for distant objects.
Question : Comprehension:
Read the following passage and answer the questions that follow.
Rajasthan's farmers have been banging plates and lighting fires these days. It is their desperate attempt to scare away the swarms of migratory locusts invading their fields and eating away crops. The pest attack has come as a double blow for farmers already reeling under the impact of the COVID lockdown.
Millions of locusts, covering 1-4 sq km of the skyline, have reached 10 of the state's 33 districts within three weeks of being first spotted on April 30. Last year, yellow locusts entered India from Pakistan in the second half of May. The attack had originated in Yemen, coming all the way to West Asia, Pakistan, and then India, creating havoc in 17 countries en route.
With the harvest nearly over in Rajasthan, the invading population of grasshoppers this May is feeding mainly on sprouting cotton crops sown last month, vegetables, and fodder. State officials, though, fear damage to the young millet and moong dal crops due in July and August if the locusts breed.
Flying in through the Pakistan border near Jaisalmer, the locust swarms have infiltrated as deep as Kishangarh in Ajmer district. Locusts can cover 200–250 km in a day if they get wind support. Presently, the dust storms sweeping parts of Rajasthan are aiding their flight. Officials said the Union Agriculture Ministry's Locusts Warning Organisation (LWO) is in the process of acquiring 60 vehicles with mounted insecticide sprayers from abroad by July. Ten such vehicles were purchased this January.
"Immature pink locusts are very active, which is why they have reached the interiors of Rajasthan [from Pakistan] so quickly," says K.L. Gurjar, deputy director, of LWO. Their metabolism slows down during winters, but in summers, they can fly from 4 am to 8 pm, covering long distances and consuming more crops along the way than mature locusts would. The LWO has put 10 insecticide-spraying vehicles on the job in Rajasthan. The Rajasthan government has provided rented tractors, on which insecticide sprayers are mounted, and also the manpower to man them. The centre-state joint operation has so far cleared a few hundred sq km of fields of the locusts. Preliminary estimates put the loss to crops at a few crore rupees.
State officials say there is an urgent need to contain the pink locusts before they start breeding in the next few weeks. Indiscriminate aerial spraying of insecticides is ill-advised, as this can damage crops as well as affect human settlements.
One of the strategies being considered now is to use fixed-wing aircraft for ultra-low volume spraying of chemicals. The state government may request such aerial sorties from the Air Force. Drones have limited capabilities as they can carry only about 20 litres of insecticide at a time, making them effective only over small areas.

Option 2: Phosphine
Option 3: Carbon Tetrachloride
Option 4: Phosphorous Trichloride

Question : Select the option that expresses the given sentence in passive voice. The employer paid him the salary.
Option 1: He was paid by the employer salary.
Option 2: He was being paid the salary by the employer.
Option 3: The salary was paid to him by the employer.
Option 4: He had been paid the salary by the employer.
Correct Answer: The salary was paid to him by the employer.
Solution : The correct choice is the third option.
Passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active sentence becomes the subject in the passive voice.
The structure of the passive voice in the case of the simple past tense is: Singular object + was + past participle of the main verb + by + agent of the action.
Therefore, the passive sentence would be: The salary was paid to him by the employer.

We live in (1)_____ age of wonders and miracles. It has been called the 'Age of Science', and different aspects of our lives that changed in the (2)______ centuries have been attributed to science. This is completely true, but it is only one side of the coin. The flip side is that as we have advanced more in the field of technology, something fundamental to humanity has been left behind. Values such as empathy and concern for our fellow human beings are gradually being eroded due to the onslaught of our ever-evolving lifestyles, aided by the marvels of technological advancements. Take the example of the Internet. On one hand, access to information and knowledge at the click of a button is a veritable boon to everyone (especially students), and this has made our lives much simpler. On the other hand, it has severely limited actual contact with teachers, friends, and elders. Thus, the learning that a person (3)_______ is incomplete as he or she cannot easily take the advice that another person can give on the basis of knowledge and practical experience that is at his or her disposal. Today, a small child can access and navigate the Internet with an ease that still astounds (4)_________ from the older generation. But what is even more astounding is the neglect of the basic human traits of friendship, relationships, and family values. Owing to all the technological advancements and gadgets available today, children often miss out on the most enriching childhood experiences, such as playing outdoor games with friends, which (5)_______ from being immensely enjoyable and physically exhilarating, also develops traits such as teamwork and discipline at an early age.

Therefore, the correct answer is apart.

Question : Directions: In the following question, some parts of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No Error".
Many a man have (1) / come to India from Canada (2) / to live here permanently. (3) / No Error (4)
Solution : The error lies in the first part of the sentence.
In the first part, "Many a man have" should be replaced with "Many a man has". When many a is used, it should be followed by a singular verb, so has (singular) should be used instead of have (plural).
Therefore, the correct sentence is: Many a man has come to India from Canada to live here permanently.
Question : Directions: In the following question, a series is given with one number missing. Select the missing number from the given alternatives. 33, 10, 43, 53, 96, ?
Option 1: 150
Option 2: 163
Option 3: 171
Option 4: 149
Correct Answer: 149

Each number is the sum of the previous two terms – 33 + 10 = 43; 10 + 43 = 53; 43 + 53 = 96; 53 + 96 = 149
So, the required term is 149. Hence, the fourth option is correct.
