All questions of Assertion and Reasoning for SSC CGL Exam

Assertion (A) is true. Areas near the Equator typically experience rainfall throughout the year. This region often encounters a consistent amount of precipitation due to its proximity to the Intertropical Convergence Zone (ITCZ), where air masses converge, leading to consistent upward motion and subsequent rainfall.

Reason (R) is also true. High temperatures and high humidity near the Equator create conditions favorable for the formation of conventional or convective rainfall. This happens when the warm air rises, cools, condenses, and forms clouds, often resulting in afternoon showers or thunderstorms.

Therefore, both assertions are accurate, and the reason (R) effectively explains why areas near the Equator receive rainfall throughout the year due to the prevailing weather conditions and the mechanisms behind rainfall in those regions.

Ice floats on water and is in solid state because ice is less dense than water. Both the assertion and reason are correct but the stated reason is not the correct explanation of the assertion.
Hence, 'Both Assertion and Reason are true but Reason is not the correct explanation of Assertion' is the correct answer

The doctrine of Lapse was adopted as an annexation policy with respect to the expansionist tendencies of the British East India Company.

And according to the policy, if a ruler was incompetent or left without a male heir to the throne, the state was bound to lose its princely status.

So, the assertion is correct.

Also, this policy was widely implemented by Lord Dalhousie, who was the Governor-General of the East India Company in India between 1848 and 1856 but actually the policy was drafted in 1847.

So, the stated reason is correct but does not explain the assertion.

The assertion is correct because it is true that rocket science is also built upon the basic concepts of Newton with a complex calculation and numerous possibilities.
Hence, the assertion is true.

But the reason is not correct as it says that anyone can make a rocket on his own which is logically inconsistent.
Therefore, the reason is false.

Hence, A is true, but R is false.

Based on the given situation and possible reasons, let's analyze each option and determine which one/s is/are correct:
I. OTT services provided by the given platforms can only be accessed through specific streaming devices manufactured by their respective providers. → This reason is incorrect in relation to the given situation. The difficulty in finding high-quality and engaging documentaries in the regional language is not related to the requirement of specific streaming devices. The issue mentioned is specifically about finding documentaries in a particular language, not the technical compatibility of devices.

II. OTT services provided by the given platforms primarily focus on live TV broadcasts and do not offer on-demand content. → This reason is incorrect in relation to the given situation. The focus mentioned here on live TV broadcasts does not align with the scenario of Anjali encountering difficulties in finding documentaries. It does not explain the specific challenge of finding regional language documentaries.

III. The cumulative cost of subscribing to multiple OTT platforms makes it harder to keep up with all the content across these platforms, and it becomes overwhelming. → This reason is incorrect in relation to the given situation. The difficulty in finding high-quality and engaging documentaries in the regional language is not related to the cumulative cost of subscribing to multiple OTT platforms. 

IV. Regional documentaries do not receive the same level of promotion and visibility as mainstream movies and TV series on the given OTT platforms, which leads to documentaries being overshadowed by trending content. → This reason is correct in relation to the given situation. The reason explains the dominance of trending content and popular shows on OTT platforms making it harder to discover them.

Hence, the correct answer is Only IV.

Assertion (A) states that Sun is a star which is a fact. The Sun is classified as a G-type main-sequence star in the astronomical classification, or a G Dwarf star or a yellow dwarf.

Reason (R) says, stars are space objects that produce their own energy through the fusion reaction of gases, which is also a fact. Stars, including the Sun, generate their energy by the process of nuclear fusion in their cores, mostly converting hydrogen into helium.

Therefore, (R) is the correct explanation of (A). It is the fact that stars produce their own energy through nuclear fusion that categorizes the Sun as not just a celestial body, but specifically a star.

Hence, Both ‘A’ and ‘R’ are true and ‘R’ is the correct explanation of ‘A’.

The use of chlorofluorocarbons is banned nowadays because these cause holes in the ozone layer through which ultraviolet rays penetrate and may cause skin cancer.

Ventilators are provided near the roof as the air upon heating, rises and so can be thrown out of a room through high ventilators.

Hence, A is true but R is false.

Vehicles emit carbon dioxide which is a greenhouse gas.

Therefore, Reason (R) is true.

Therefore, increase in average cars on road means increase in carbon emissions.

Therefore, Assertion(A) is true.

Hence, (A) is true and (R) is true and (R) is the correct explanation of (A).

Leakages in household gas cylinders can be detected because of the strong smell of ethyl mercaptan mixed with LPG.

Assertion (A) is true. On the equinoxes, which occur twice a year (around March 20th and September 22nd), the day and night are approximately equal in duration all over the globe. This is because the Earth's axis is neither inclined toward nor away from the Sun, resulting in nearly equal sunlight distribution across the Earth.

Reason (R) is also true. During the equinoxes, the position of the Earth with respect to the Sun is such that neither pole is inclined toward the Sun. This lack of inclination is why the sunlight falls almost equally on both hemispheres, resulting in the equal length of day and night across the globe.

The husk of unpolished rice contains Vitamin B1, deficiency of which causes the disease Beriberi.

So, the rice should be eaten unpolished.

The low electrical resistance of copper makes it a good electric conductor.

So it is used to make electric wires.

Option A cannot be the correct reason as reporting a significant drop in profits would generally lead to a decrease in demand for the company's stocks.

Option B cannot be the correct reason as being involved in a major scandal involving environmental violations would also have a negative impact on the company's reputation and stock price.

Option C cannot be the correct reason as the resignation of key executives might raise concerns about the stability and future prospects of the company, potentially leading to a decrease in demand for its stocks.

Option D is likely to be the most plausible reason for the surge in demand for Company XYZ's stocks and the subsequent increase in stock price. A major technological breakthrough can generate excitement and optimism among investors, leading to increased demand for the company's stocks.

Hence, the correct answer is 'The company has recently announced a major breakthrough in its technology'.

It is true that black money is a big problem in India and that the prices of goods are increasing rapidly in the country. But the reason is not the complete explanation behind the assertion.

The gulf is a portion of the sea that is almost surrounded by land but has one narrow opening.

It is formed as a result of a collapse of a giant rock or sinking of the lank which leads to the creation of a gap (indentation) and the seawater rushes to occupy the space. So, both A and R are true and R is the correct explanation of A.

 Hence, option 1 is correct. 

Ventilators are provided near the roof as the air upon heating, rises and so can be thrown out of a room through high ventilators.

It is true that honey is sweet in taste.
Therefore, the assertion is true.

The reason mentioned is also true that honey is collected by honeybees.

Hence, Both A and R are true and R is not the correct explanation of A.

Assertion (A) states that no food material normally enters the windpipe during swallowing, which is true because the process of swallowing involves the epiglottis covering the opening of the windpipe to prevent food or liquid from entering it.

Reason (R) explains this by highlighting that during swallowing, the back portion of our tongue covers the opening of the windpipe with the epiglottis, ensuring that food or drink is directed towards the esophagus rather than entering the windpipe.

Option (a) affirms that both A and R are true, and R provides the correct explanation for A, as the action of the tongue and epiglottis working together helps prevent food from entering the windpipe during swallowing.

Seeds are treated with fungicides before sowing to avoid seed-borne diseases. However, seeds may germinate, even if not treated with a fungicide solution.
