EduRev UPSC answered
1. Statement 1 is correct. Indian deep tech start-ups do face significant funding challenges because they are perceived as high-risk by investors. This perception limits their potential for securing necessary funding to innovate and remain competitive.
2. Statement 2 is correct. The scalability of Indian start-ups is indeed constrained by a domestic market with limited spending power. It is noted that 90% of the population cannot significantly contribute to growth, which hampers the ability of start-ups to scale effectively within the country.
3. Statement 3 is incorrect. India does not primarily rely on its domestic electric mobility and battery technology for global competitiveness. Instead, it is mentioned that India lags behind in these areas and heavily relies on advancements from countries like China.
Thus, the correct answer is Option B: 1 and 2 Only, as only statements 1 and 2 accurately reflect the challenges and limitations faced by the Indian start-up ecosystem in the context of deep technology and innovation.

EduRev UPSC answered
The distinctive feature that separates the male Pale-Chinned Flycatcher's dull blue-grey head and breast is the pale chin or throat patch. This feature is particularly notable in distinguishing the male from the female of this species. The pale chin or throat patch is a key characteristic of the male's appearance, adding to the bird's unique and subtle beauty.

Consider the following pairs regarding the phases of the El Niño Southern Oscillation (ENSO):
1. El Niño : Cooler-than-usual sea surface temperatures
2. La Niña : Warmer-than-usual sea surface temperatures
3. ENSO-Neutral : Transitional phase between El Niño and La Niña
4. El Niño : Associated with unusual global warming patterns
How many pairs given above are correctly matched?
  • a)
    Only one pair
  • b)
    Only two pairs
  • c)
    Only three pairs
  • d)
    All four pairs
Correct answer is option 'B'. Can you explain this answer?

1. El Niño : Cooler-than-usual sea surface temperatures - Incorrect. El Niño is characterized by warmer-than-usual sea surface temperatures in the central and eastern tropical Pacific Ocean.
2. La Niña : Warmer-than-usual sea surface temperatures - Incorrect. La Niña involves cooler-than-usual sea surface temperatures, often leading to colder atmospheric patterns and stronger trade winds.
3. ENSO-Neutral : Transitional phase between El Niño and La Niña - Correct. ENSO-Neutral is indeed the transitional phase where neither El Niño nor La Niña dominates, resulting in less certain weather forecasts.
4. El Niño : Associated with unusual global warming patterns - Correct. El Niño is associated with unusual global warming patterns due to the increased sea surface temperatures affecting global climate.
Thus, pairs 3 and 4 are correctly matched, making two pairs correctly matched in total.

Divey Sethi answered
Statement-I is correct as the Navkar Mahamantra Divas indeed promotes peace, non-violence, and spiritual harmony through collective chanting of the Navkar Mantra, as mentioned in the provided information. Statement-II is also correct as the Jain philosophy does emphasize that the world is created and maintained by Universal Law, Universal Truth, Universal Faith, and Universal Soul, as outlined in the details provided. However, Statement-II does not directly explain or relate to Statement-I. The two statements are correct independently but do not have a direct explanatory relationship.

What is the primary function of a catalyst in a chemical reaction?
  • a)
    To decrease the activation energy of the reaction
  • b)
    To increase the concentration of reactants
  • c)
    To change the equilibrium constant of the reaction
  • d)
    To alter the stoichiometry of the reaction
Correct answer is option 'A'. Can you explain this answer?

A catalyst in a chemical reaction primarily functions to decrease the activation energy required for the reaction to occur without being consumed in the process. By providing an alternative reaction pathway with a lower activation energy, a catalyst speeds up the rate of the reaction. This allows the reaction to proceed faster and at lower temperatures, making it more efficient.

Consider the following statements regarding Type 5 Diabetes:
1. Type 5 Diabetes primarily affects obese individuals in high-income countries.
2. It is characterized by malnutrition-induced reduction in insulin production.
3. Unlike Type 2 Diabetes, Type 5 Diabetes is often associated with autoimmunity.
Which of the statements given above is/are correct?
  • a)
    1 Only
  • b)
    1 and 2 Only
  • c)
    2 Only
  • d)
    1, 2 and 3
Correct answer is option 'C'. Can you explain this answer?

K.L Institute answered
Statement 1 is incorrect. Type 5 Diabetes primarily affects lean, undernourished teenagers and young adults in low- and middle-income countries, not obese individuals in high-income countries. This condition is distinct from Type 2 Diabetes, which is more commonly associated with obesity.
Statement 2 is correct. Type 5 Diabetes is indeed characterized by a malnutrition-induced reduction in insulin production. This is a key distinguishing feature of this form of diabetes and sets it apart from the more common Type 2 Diabetes, which is primarily related to insulin resistance.
Statement 3 is incorrect. Unlike Type 1 Diabetes, which is associated with autoimmunity, Type 5 Diabetes does not have an identified autoimmune or genetic basis. It is primarily linked to nutritional deficiencies rather than autoimmune processes.
Therefore, only Statement 2 is correct, making Option C the correct choice.

Consider the following statements:
Statement-I:
The suspension of the 1972 Simla Agreement by Pakistan may lead to increased hostilities along the Line of Control (LoC).
Statement-II:
The lack of a formal agreement between India and Pakistan could potentially pave the way for third-party mediation in the Indo-Pak conflict.
Which one of the following is correct in respect of the above statements?
  • a)
    Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
  • b)
    Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I
  • c)
    Statement-I is correct, but Statement-II is incorrect
  • d)
    Statement-I is incorrect, but Statement-II is correct
Correct answer is option 'B'. Can you explain this answer?


Statement-I correctly highlights the potential consequence of the suspension of the 1972 Simla Agreement by Pakistan, indicating the increased risk of hostilities along the Line of Control (LoC). This aligns with the information provided in the source material about heightened tensions and potential conflict escalation.
Statement-II correctly observes that the absence of a formal agreement between India and Pakistan might create opportunities for third-party mediation in the Indo-Pak conflict. While this statement is accurate in the context of the source material, it does not directly explain or elaborate on Statement-I. Instead, it presents a separate potential implication of the agreement's suspension.
Therefore, both statements are individually correct in accordance with the information provided, but Statement-II does not directly provide an explanation for Statement-I, making option (b) the correct answer.

Lakshya Ias answered

Both Statement-I and Statement-II are correct in the context of the provided information. Statement-I highlights the alignment between trans-exclusionary feminism and far-right ideologies, illustrating how trans women are often portrayed as threats. Statement-II correctly points out that the U.K. Supreme Court's decision has implications for the Gender Recognition Act, 2004, casting doubts on the equality provisions within the law. Furthermore, Statement-II explains the broader impact of the court ruling on the legal framework concerning transgender rights, thereby substantiating Statement-I. Hence, option (a) is the correct choice as both statements are accurate, and Statement-II indeed provides additional context that supports Statement-I.

    To increase profits for the shipping industry
  • b)
    To penalize smaller vessels for maritime emissions
  • c)
    To reduce greenhouse gas emissions from commercial shipping
  • d)
    To exempt large vessels from emission regulations
Correct answer is option 'C'. Can you explain this answer?

The primary goal of the global carbon tax supported by India and other nations is to reduce greenhouse gas emissions from commercial shipping.

By implementing this tax, the international community seeks to significantly decrease maritime emissions and combat climate change.

Consider the following statements regarding India's subsea cable infrastructure:
1. India hosts 17 international undersea cables, with the majority concentrated in a specific area in Mumbai.
2. India contributes 5% to the global subsea cable systems.
3. The deployment of undersea cables in India is hindered by extensive regulatory requirements, with a significant portion of project time spent on regulatory compliance.
Which of the statements given above is/are correct?
  • a)
    1 Only
  • b)
    1 and 2 Only
  • c)
    1 and 3 Only
  • d)
    1, 2 and 3
Correct answer is option 'C'. Can you explain this answer?

1. Statement 1: This statement is correct. India has 17 international cables that land in the country, and a significant concentration of these cables is in a 6-km stretch in Versova, Mumbai. This highlights the major hubs for India's subsea cable infrastructure, which include Mumbai and Chennai.
2. Statement 2: This statement is incorrect. India contributes only 3% to the global subsea cable systems, not 5%, indicating its underrepresentation in the global network. This is a critical point as it reflects India's relatively small footprint in the global subsea cable ecosystem.
3. Statement 3: This statement is correct. The deployment of undersea cables in India indeed faces significant challenges due to the extensive regulatory requirements. It is reported that 80% of the project time is spent on dealing with regulatory compliance, which involves navigating about 51 permissions from various departments, including the Department of Telecom, Ministry of Environment, and Ministry of Home Affairs. This poses a considerable hindrance to the timely deployment of subsea cables.
Therefore, statements 1 and 3 are correct, while statement 2 is not. Thus, the correct answer is Option C: 1 and 3 Only.
