1. Who among the following release World Press Freedom Index?

1. Reporters Without Borders
2. World Economic Forum
3. World Bank
4. Economic Intelligence Unit

Ans.  A

Explanation

World Press Freedom Index is released by the Reporters Without Border. India has been ranked 142 out of 180 countries dropping 2 places from 140. Internet blackout in Kashmir was the major factor causing the downgrading in the ranking. Norway is at the top while China is at 177 and North Korea at 180. World Press Freedom Day is observed every year on 3 May.

Hence, the correct answer is A.

 

2. Which of the following orbits is best for the satellites making Satellite TV possible?

1. Geostationary transfer orbit
2. Geostationary orbit
3. Low Earth orbit
4. Polar orbit

Ans. B

Explanation

Geostationary orbit, also called geosynchronous equatorial orbit, is a circular orbit around the equator and the period of rotation of satellite in this orbit is equal to that of Earth’s orbit i.e one sidereal day. So, the satellite appears to be at a fixed position. So the ground antennas can be placed in one direction while receiving the data.

Geostationary Transfer Orbit is an elliptical geosynchronous orbit between two circular orbits and is used to transfer satellites from one circular orbit to the other circular orbit of different radii.

Polar orbit is an orbit in which satellite passes above the two poles of the planet by making an angle of 90° with the equator. In this way, it passes through the planet by making different longitudinal angles with the equator.

Low Earth orbit operates at 500 km to 2000 km above the Earth’s surface as against geostationary orbit which operates at around 36000 km above Earth’s surface. This orbit is used for communication because it allows the transmission at low latency as compared to geostationary orbit but in this orbit, for communication to take place many satellites are required (space debris).

Also since a satellite can complete one revolution around Earth in 120 minutes so satellites may be observed at different points. For this many satellites has to work in tandem to pass on the role to ensure seamless communication.

Hence, the correct answer is B.

 

3. Which of the following is true about African Swine Fever?

1. The virus belongs to Asfarviridae family of viruses.
2. The virus has a double-stranded DNA virus.
3. It is not caused by humans.

Select the correct answer from the codes given below:

1. 1,2,3
2. 1 and 3
3. 1 only
4. 3 only

Ans. A

Explanation

Assam is witnessing the outbreak of African Swine Fever. The fever is caused by the virus belonging to the family of Asfarviridae. The virus is made up of double-stranded DNA. It causes hemorrhagic fever and the mortality rate is high among the pigs. Some natural hosts, warthogs, bushpigs, and soft ticks act as the vector but it does not cause disease among humans. It affects only pigs.

Hence, the correct answer is A.

 

4. Which of the following is true about Llamas?

1. They belong to the family of camels.
2. They are endemic to South America.
3. The fiber of Llamas is used in making ropes.

Select the correct answer from the codes given below:

1. 1 only
2. 1 and 3
3. 1,2 and 3
4. 2 and 3

Ans. B

Explanation

There are chances that Llamas have antibodies against COVID-19 and the research is going on in this regard. Llamas belong to the family of camels and are widely found in Andes ranges. It is domesticated in South America for its hide, fur, etc. Its fur is used in making undercoats, ropes, rugs, etc. At present, they are naturally found in South America though they have been imported to North America.

Hence, the correct answer is C.

 

5. Which of the following is true about NAM?

1. The NAM principles were developed in Belgrad in 1961.
2. The 2018 summit to place in Venezuela in South America.
3. Both statements are true.
4. None of the above is true.

Ans. B

Explanation

Non-Aligned Movement is a forum of 120 countries that come together to take on the issues of various developing countries. The principles of NAM were discussed in 1955 in the Bandung conference during the cold war era to to promote the countries not to side with any of the blocks formed. It was established with its 1^st conference in 1961 in Belgrade, Yogoslavia.

It is based on the Panchsheel principles i.e mutual respect, territorial integrity and sovereignty, mutual non-aggression, mutual non-interference in domestic affairs, equality and mutual benefit, and peaceful co-existence. The 2019 summit was held in Baku, Azerbaijan and the 2020 summit was held through video conferencing.

Hence, the correct answer is B.
