RRB Junior Stenographer Mock Test - 9 - RRB NTPC/ASM/CA/TA MCQ

Option 2 is correct.

• Carbon monoxide (CO) is one of the most serious air pollutants, highly poisonous to living beings because of its ability to block the delivery of oxygen to the organs and tissues.
• It binds to haemoglobin to form carboxyhemoglobin, which is about 300 times more stable than the oxygen-haemoglobin complex.
• In blood, when the concentration of carboxyhemoglobin reaches about 3–4 per cent, the oxygen-carrying capacity of blood is greatly reduced.
• This oxygen deficiency results in headache, weak eyesight, nervousness and cardiovascular disorder.

General Service Enlistment Act of 25 July 1856 espoused that the Bengal Army shall take upon the responsibility of serving overseas, if need be. Out if the three Presidencies, only the armies of Bombay and Madras had the obligation of serving overseas, as such they faced immense strain for deployment at Burma and China fronts. The General Services Enlistment Act called for the same from Bengal Army as well that faced great resentment because they were initially exempted from overseas operations.

The New Enlistment Act of 1856 entailed that every unit of the Bengal Army was accountable for servings overseas, if asked to do so. Though this was applicable to only the new recruits of the Bengal Army, the older recruits feared that they too would be asked to do so and hence they resented.

Let AB be the building and the man is standing at A.

When the car is 200m away from the building, the angle of depression is 60°

tan 60° = BD/AB = √3

⇒ 200/AB = √3

⇒ AB = 115.47 m

⇒ tan30° =BC/AB = x/115.47 = 1/√3

⇒ x = 66.67

Now, the car travels distance CD in 8 seconds

 CD = BD – BC = 200 – 66.67 = 133.33 m

 Speed = 133.33/8 = 16.67 m/s

Weight of the car = (180 × 7 – 72 × 6) = 828 kg
Hence, Option B is correct.

The average weight of A, B, C and D = 68 kg
The average weight of A, B, C, D and E = 70 kg
So the answer = 70 × 5 – 68 × 4 = 78 kg
Hence, Option A is correct.

• The Treaty of Peace of Paris restored to the French their factories in India. Hence, statement 1st is correct. 

•  

  English became the supreme European power in the Indian subcontinent since the Dutch had already been defeated in the battle of Bidara in 1759. Hence, statement 2nd is incorrect. 

•  

  The decisive Battle of the third Carnatic War was won by the English in Wandiwash in Tamilnadu. Hence, statement 3rd is correct. 

From the diagram given below:

The shaded part represents the singers, who are directors but not actors.

Hence, the correct answer is "7".

The correct answer is A and R both are true and R is the correct explanation of A.

Key Points

Trees as a shelter for animals:

• Trees provide shelter and food for a variety of birds and small animals, such as squirrels and beavers.
• Enhancing growth diversity, trees create an environment that allows the growth of plants that otherwise would not be there.
• Flowers, fruits, leaves, buds, and woody parts of trees are used by many different species.
• Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. 

Deforestation can lead certain tree species to permanently disappear, which affects the biodiversity of plant species in an environment.

Hence, the reason is also correct.

Important Points

Human activities that influence the extinction and endangerment of wild species fall into a number of categories:

• ​Land use practices like Deforestation, Projects in urban and suburban development, agriculture, and water management projects that encroach upon and destroy natural habitats.
• Unsustainable hunting and harvesting result in higher rates of death than new individual recruitment.
• Ecological damage caused by water, air, and soil pollution.
• Anthropogenic (human-caused) global climate change.
• ​According to the India State of Forest Report (ISFR) 2019, The forest and tree cover in the country is estimated at 80.73 million hectares, which is 24.56 percent of the total geographical area.​

Additional Information

The International Union of Conservation of Nature and Natural Resources (IUCN):

• For the purposes of conservation, the IUCN has divided the threatened plant and animal species into 9 categories.
• Endangered Species: It includes those species which are in danger of extinction. The IUCN's Red List of Threatened Species provides information about endangered species around the world.
• Vulnerable Species: This includes the species which are likely to be in danger of extinction in the near future if the factors threatening their extinction continue.
• Rare Species: The population of these species is very small in the world; they are confined to limited areas or thinly scattered over a wider area.

(i) The COD (Chemical oxygen demand) test is used to measure the content of organic matter of waste water, both biodegradable and non-biodegradble.

(ii) The COD test uses potassium dichromate (K₂Cr₂O₇) in presence of concentrated sulfuric acid (H₂SO₄) solution that oxidizes both organic (predominate) and inorganic substances in a waste water sample.

(iii) The reagents for COD test are followings:

• Standard potassium dichromate solution (0.25N)
• Concentrated sulfuric acid
• Standard ferrous ammonium sulphate titrant (0.1N)
• Ferroin indicator solution.

• Mahatma Gandhi led the Civil Disobedience Movement that was launched in the Congress Session of December 1929. The aim of this movement was a complete disobedience of the orders of the British Government.

• During this movement, it was decided that India would celebrate 26th January as Independence Day all over the country. On 26th January 1930, meetings were held worldwide, and the Congress tricolour was hoisted.

• The British Government tried to repress the movement and resorted to brutal firing, killing hundreds of people. Thousands were arrested along with Mahatma Gandhi and Jawaharlal Nehru, but the movement spread to all the country's four comers.

• Following this, Round Table Conferences were arranged by the British and Mahatma Gandhi attended the second Round Table Conference at London. But nothing came out of the conference, and the Civil Disobedience Movement was revived.

• During this time, Bhagat Singh, Sukhdev and Rajguru were arrested on the charges of throwing a bomb in the Central Assembly Hall (which is now Lok Sabha) in Delhi, to demonstrate against the autocratic alien rule. They were hanged to death on March 23, 1931.

On April 7, 1934, the civil disobedience movement came to a stop. The Simon Commission was a group of seven British Members of Parliament of the United Kingdom, under the chairmanship of Sir John Simon. The Commission arrived in British-occupied India in 1928 to study constitutional reform.

From the common explanation, we can say that R sits 3rd to the right of the one who sits immediate right of M. 
Hence, Option D is correct.
Final Arrangement:

Common Explanation:
References:
Only two boys sit to the left of J.
Eight boys sit between R and J.
Only three boys sit between R and M.
Inferences:
From the above references, we get two different cases:

References:
P sits fourth to the right of R.
O sits third to the left of M.
Inferences:
So, from this case 2 will be eliminated as P sits fourth to the right of R.

References:
Only three boys sit between O and H.
T sits third to the right of M.
V sits fourth to the right of O.
More than 12 boys sit between P and H.
More than seven boys sit between P and J.
Inferences:
From the above reference, we get the final arrangement:

• The heat is transferred in form of conduction, convection, and radiation. 
• Radiation is the mode of heat transfer that does not require a medium. It happens through infrared radiation. 
• The infrared radiations are electromagnetic waves having a frequency less than the visible spectrum. 
• The infrared radiation is emitted from every hot body. 
• Earth is heated by infrared radiations of the sun. The radiations are reflected back by the earth which is captured by greenhouse gases. 
• The greenhouse gases absorbers some amount of heat and keeps the earth warm. 

Thus, infrared radiation is trapped on the earth’s surface by the greenhouse effect.

Additional Information

• The major Greenhouse gas is Carbon dioxide followed by methane, water vapor, and nitrous oxide.  
• UV rays have a frequency higher than violet and they help in the formation of Ozone. 
• The wavelength of different electromagnetic waves are given in the below diagram. 

80 men × 40 = 50 women × 40
80 men = 50 women
1 man : 1 woman = 5 : 8

Hence, Option D is correct.
