Q1. Which of the following statements about the Chenab Bridge is correct?
A) The bridge connects Udhampur to Srinagar.
B) The bridge will be operational by January-February 2024.
C) The bridge is shorter than the Eiffel Tower in Paris.
D) The bridge is a crucial link between Delhi and Kashmir.
Answer: B
Explanation: The Chenab Bridge is said to be the world's highest railway bridge and is located between two hill slopes at a height of 359 m, which is taller than the Eiffel Tower in Paris. The bridge spans a length of 1.3 km and will be a crucial link between Kashmir and the rest of India. However, the bridge will pave the way for trains to run along the Udhampur-Srinagar-Baramulla Rail Link (USBRL) project seamlessly, indicating that option A is incorrect. Option C is also incorrect as the bridge's height is specifically mentioned as taller than the Eiffel Tower.
Option D is incorrect as the bridge connecting Kashmir to the rest of India, not Delhi specifically.
Therefore, option B is the correct answer as the bridge will be operational by January-February 2024.
Q2. Which of the following statements about Marburg virus disease (MVD) is correct?
A) MVD is caused by bacteria.
B) MVD has a fatality rate of 100%.
C) African green monkeys were the natural hosts for the Marburg virus.
D) There is no approved antiviral treatment or vaccine for MVD as of now.
Answer: D
Explanation: The Marburg virus disease (MVD) is a severe, often fatal hemorrhagic fever caused by a filovirus similar to Ebola. The natural hosts for the Marburg virus are Rousettus fruit bats, not African green monkeys, as mentioned in option C. The MVD has an average fatality rate of around 50%, which rules out option B. The disease is diagnosed through lab testing of samples and cannot be clinically distinguished from diseases such as malaria, typhoid fever and other viral hemorrhagic fevers. There is no approved antiviral treatment or vaccine for MVD as of now, making option D the correct answer.
Option A is incorrect as MVD is caused by a virus, not a bacteria. Therefore, option D is the correct answer.
Q3.Which of the following statements is/are true about the Aravalli Green Wall Project?
1)It is a part of the Union Environment Ministry's vision to create green corridors across the country.
2)The project covers the states of Haryana, Rajasthan, Gujarat and Delhi.
3)The project will involve planting native species of trees and shrubs, restoring surface water bodies and focusing on agroforestry and pasture development.
4)The project aims to combat land degradation, prevent the expansion of the Thar Desert, and reduce soil erosion, desertification and dust storms.
5)The project will be executed by central and state governments, forest departments, research institutes, civil society organisations, private sector entities and local communities.
A) 1,2,3 only
B) 2,3,4,5 only
C) 4 & 5 only
D) All of the above
Answer: All of the above (1, 2, 3, 4, 5)
Explanation: The Aravalli Green Wall Project is a part of the Union Environment Ministry's vision to create green corridors across the country to combat land degradation and desertification. It covers the states of Haryana, Rajasthan, Gujarat and Delhi, where the Aravalli hills landscape spans over 6 million hectares of land. The project involves planting native species of trees and shrubs on scrubland, wasteland and degraded forest land, along with rejuvenating and restoring surface water bodies such as ponds, lakes and streams. The project also focuses on agroforestry and pasture development to enhance the livelihoods of local communities. The project aims to combat land degradation, prevent the expansion of the Thar Desert, and reduce soil erosion, desertification and dust storms. It will be executed by various stakeholders such as central and state governments, forest departments, research institutes, civil society organisations, private sector entities and local communities. Adequate funding, technical skills, policy coordination and public awareness will be called upon to ensure the success of the project.
Q4. What is the Earth's magnetosphere?
A) A layer of gases that protects the Earth from harmful solar radiation
B) The region around the Earth that is affected by its magnetic field
C) A layer of electrically charged particles that surround the Earth
D) The boundary between the Earth's atmosphere and outer space
Answer: B
Explanation: The Earth's magnetosphere is the region around the Earth where the magnetic field of the Earth is dominant and protects us from the charged particles of the solar wind emitted by the Sun. When a coronal mass ejection (CME) or high-speed solar wind stream interacts with the magnetosphere, it can cause a magnetic storm which is characterized by a rapid drop in the Earth's magnetic field strength that lasts for several hours, followed by a gradual recovery over a period of several days.
Q5.Which of the following pairs are correctly matched?
1. Article 20(1): Ex-post-facto law
2. Article 20(2): Double Jeopardy
3. Article 20(3): Right against self-incrimination
(A) only 1
(B) Only 2
(C) Only 3
(D) All of the above
Answer:D
Explanation:
Article 20 of the Indian Constitution deals with protection against conviction for offences. It provides three fundamental protections to an accused person.
Article 20(1): Ex-post-facto law - It prohibits the application of ex-post-facto laws, which means that a person cannot be convicted for an act which was not an offence at the time it was committed.
Article 20(2): Double Jeopardy - It prohibits a person from being punished for the same offence twice. This means that a person who has been acquitted or convicted of an offence cannot be tried again for the same offence.
Article 20(3): Right against self-incrimination - It prohibits a person from being compelled to be a witness against himself. This means that a person cannot be forced to give testimony that will incriminate himself.
