The government has emergency powers under Section 69A of the Information Technology Act to block any content where it is satisfied that it is against the country’s sovereignty, integrity, and defense, and in such cases, the law does not require it serving any prior notice to the concerned content providers before ordering a ban. TikTok, Shareit, Mi Video Call, Club Factory, and Cam Scanner, citing threat to national security and sovereignty have thus been banned in India. The ban comes amid continuing tensions on the border between India and China and covers a variety of applications from e-commerce to gaming, social media, browsers, instant messaging and file sharing.

India and Myanmar have agreed to work towards the operationalization of the Sittwe port in the Rakhine state in the first quarter of 2021. Situated at the mouth of the Kaladan River, the Sittwe Port is being financed by India as a part of the Kaladan Multi-Modal Transit Transport Project, a collaboration between India and Myanmar. So, statement 1 is correct and 2 is not correct. The project is aimed at developing transport infrastructure in southwestern Myanmar and north-eastern India. Hence statement 3 is not correct. The announcement came post conclusion of the two-day visit of Indian Army Chief General MM Naravane and Foreign Secretary Harsh Vardhan Shringla to Myanmar. They also discussed the progress in the ongoing Indian-assisted infrastructure projects such as the Trilateral Highway and the Kaladan Multi-Modal Transit Transport Project.

Indentured labors started after the abolition of slavery. So, statement 1 is NOT correct. It was widely employed in the 18th century in the British colonies in North America and elsewhere and was not abolished after the French revolution. So, statement 2 is NOT correct.

In a bulb, when current passes through the filament, it produces light and heat both. Metals like tungsten (which are used as filament) glowing brightly may oxidize at high temperatures if normal gases are filled inside the bulb. Filling of inert gases like nitrogen and argon prevents oxidation of the filament and increase its life. So, statement is 2 is correct. Inert gases do not play any other role like increasing power efficiency, illumination, changing heat profile of the filament, etc. So, statements 1, 3, and 4 are NOT correct. They may reduce the heat emitted by the bulb to some extent as the bulb's inside is properly insulated.

Major factors are loss of top-soil due to water erosion, land degradation due to acidity, vegetal degradation with water erosion, and gully formation.

Concave mirrors are used in vehicle headlights, searchlights, etc, to send parallel rays because it allows the light rays to be focused as a single beam and gives more power to the light, which makes it more efficient for seeing and to be seen by others. If the mirror was not concave the light would be scattered which wastes energy and reduces efficiency. For this, the source of light is placed at the focus of the concave reflector. They are often used as shaving mirrors to see a larger image of the face. The dentists use concave mirrors to see large images of the teeth of patients. Large concave mirrors are used to concentrate sunlight to produce heat in solar furnaces. 

The World Happiness Report is an annual publication of the United Nations Sustainable Development Solutions Network. Finland is ranked as the world's happiest nation for the third consecutive year in 2020. India, previously ranked at 140 dropped to 144. It ranks 144 in the index 2020. The UN Sustainable Development Solutions Network (SDSN) was set up in 2012 under the auspices of the UN Secretary-General. SDSN mobilizes global scientific and technological expertise to promote practical solutions for sustainable development, including the implementation of the Sustainable Development Goals (SDGs) and the Paris Climate Agreement. Global Economic Prospects, World Development Report IBRD, and Ease of Doing Business by IBRD are the reports released by World Bank.

Unlike flooded rice, irrigation, when applied is not used to flood the soil but to just bring the soil water content in the root zone up to field capacity.

So, it actually reduces water consumption, and the field is not flooded or saturated. So, statements 1 and 2 are not correct.

Aerobic rice is a production system in which especially developed "aerobic rice" varieties are grown. So, statement 3 is also not correct.
