P.T. Practice Questions 12th April 2021

Q. 1 Consider the following statements about Lilavati awards:

  1. This award intends to recognize efforts being made by AICTE approved institutions only to treat women with ‘equality and fairness’ in all spheres of their lives.
  2. The objective is to create awareness about issues like sanitation, hygiene, health, nutrition using traditional Indian values.

Choose the correct option:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Ans: c (Both 1 and 2)

Explanation

This award intends to recognize efforts being made by AICTE approved institutions to treat women with ‘equality and fairness’ in all spheres of their lives. By means of this initiative, all the stakeholders (especially the girl students) in AICTE approved institutions would get a unique opportunity to present a solution to the prevalent issues of gender discrimination, such as illiteracy, unemployment, economic and nutritional disparities, maternal mortality, human rights, etc. Also, if anyone has already made a successful effort towards making a mark in the society, in establishing women’s emancipation/ empowerment at large, she/ he can showcase their efforts/ contributions. 

Objectives 

1. To create awareness about issues like sanitation, hygiene, health, nutrition using traditional Indian values. 

2. To create awareness about issues like literacy, employment, technology, credit, marketing, innovation, skill development, natural resources and rights among women. 

3. For promoting and practicing ideas of gender equity. 

4. To work towards the well-being of the girl child, adolescents, and women and focus on their development by creating awareness on gender equality. 

5. To bring about empowerment of communities, hence the footprint of such activities may also encompass neighboring/ surrounding villages/areas. 

Q. 2 Consider the following statements about climate change based on study published in the journal Biological Conservation recently:

  1. All endemic species from islands and more than four out of five endemic species from mountains are at high risk of extinction due to climate change alone.
  2. Study found that if the planet heats by over 3°C, then a third of endemic species living on land, and about half of endemic species living in the sea, face extinction.

Choose the correct option:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Ans: c (Both 1 and 2)

Explanation:

Many animals and plants unique to the world’s most scenic natural places face extinction if greenhouse gas emissions continue to rise, according to a new study published in the journal Biological Conservation. Climate change will negatively affect most native and endemic species — those that are only found in very specific places. In particular, the analysis shows that all endemic species from islands and more than four out of five endemic species from mountains are at high risk of extinction due to climate change alone.

However, remaining within the climate goals of the Paris Agreement — which aims to keep global heating well below 2°C, ideally at 1.5°C, compared to a baseline — would save the majority of species.

They found that if the planet heats by over 3°C, then a third of endemic species living on land, and about half of endemic species living in the sea, face extinction. On mountains, 84% of endemic animals and plants face extinction at these temperatures, while on islands that number rises to 100%. Overall, 92% of land-based endemic species and 95% of marine endemics face negative consequences, such as a reduction in numbers, at 3°C. Current policies put the world on track for around 3°C of heating.

Q. 3 Consider the following statements about ‘Ingenuity’ helicopter:

  1. The Mars Helicopter, Ingenuity, is a technology demonstration to test powered flight on another world for the first time.
  2. Atmosphere of Mars is 99% less dense than Earth which makes it conducive for helicopters to fly.

Choose the correct option:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Ans: a (1 Only)

Explanation

The Mars Helicopter, Ingenuity, is a technology demonstration to test powered flight on another world for the first time. It hitched a ride to Mars on the Perseverance rover. Once the rover reaches a suitable “helipad” location, it will release Ingenuity to perform a series of test flights over a 30-Martian-day experimental window beginning in early April.

Mars’ thin atmosphere makes it difficult to achieve enough lift. Because the Mars atmosphere is 99% less dense than Earth’s, Ingenuity has to be light, with rotor blades that are much larger and spin much faster than what would be required for a helicopter of Ingenuity’s mass on Earth.

Q. 4. Which of the following statements is incorrect about trade during the Pallava period?

  1. Kanchipuram was an important trading centre.
  2. Pallava had trading relations with South-east Asian countries.
  3. Barter system was not used in trade.
  4. Merchants were organised into guilds.

Answer- c

Explanation:

1)    Pallavas had trade within territory and with foreign countries. South-east Asian countries were involved in trade. On the west coast, Arabs controlled the trade and Indian traders were reduced to suppliers of goods.

2)    During this time, Kanchipuram emerged as a cultural and trading centre.

3)    Generally barter systems were used in trade. But Pallavas also issued gold and silver coins.

4)    Merchants had their own guilds- Manigramam, Nanadesi etc.
