The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.
Gear up and Make the Best Use of this initiative.
Do remember that, “the difference between Ordinary and EXTRA-Ordinary is PRACTICE!!”

Question 1 of 5
1. Question
Consider the following statements
- About 27% of the universe is made of dark energy and 68% is made of dark matter.
- While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of the universe.
Choose the incorrect statements:
Correct
Solution (a)
Statement Analysis:
Statement 1 Statement 2 Incorrect Correct · Dark matter is made up of particles that do not have a charge — which means they do not interact through electromagnetic interactions. · So, these are particles that are “dark”, namely because they do not emit light, which is an electromagnetic phenomenon, and “matter” because they possess mass like normal matter and hence interact through gravity.
· Dark energy is an unknown form of energy that affects the universe on the largest scales.
· The first observational evidence for its existence came from measurements of supernovae
· About 27% of the universe is dark matter and 68% is dark energy.
· While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of the universe. Context: James Webb telescope was in news

Question 2 of 5
2. Question
Which of the below given pairs is/are correctly matched?
Strait Connects Strait of Dardanelles The Black Sea to Sea of Marmara Strait of Magellan The Atlantic ocean and Pacific ocean Cook Strait Adriatic Sea & Ionian Sea Strait of Tartary Sea of Okhotsk and the Sea of Japan Choose the correct code:
Correct
Solution (b)
Option b Correct · The Dardanelles connects the Sea of Marmara with the Aegean Sea. · Strait of Magellan, Spanish Estrecho de Magallanes, channel linking the Atlantic and Pacific oceans, between the mainland tip of South America and Tierra del Fuego island.
· Cook Strait separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast.
· Strait of Tartary or Gulf of Tartary is a strait in the Pacific Ocean dividing the Russian island of Sakhalin from mainland Asia, connecting the Sea of Okhotsk on the north with the Sea of Japan on the south.

Question 3 of 5
3. Question
Consider the following statements about the Small Cells in 5G
- Small Cells are low-powered base stations that have a coverage range from a few metres to a few hundred metres.
- Small Cells are not needed for deploying 5G unlike earlier generations such as 4G, because of the frequency.
Choose the correct statements:
Correct
Solution (a)
Statement Analysis:
Statement 1 Statement 2 Correct Incorrect · Small Cells are low-powered radio access nodes or base stations that have a coverage range from a few metres to a few hundred metres. · They are portable, easy to deploy and help provide localised coverage.
· Small Cells provide coverage for very short distances and therefore they are installed in a large number, even more than 200 per sq. km, for good geographical coverage to provide highly reliable and high-capacity broadband.
· Small Cells are needed for deploying 5G as opposed to earlier generations such as 4G, because of the frequency. · The higher the frequency, the lower the wavelength, which means that the distance they travel is less.
· For higher frequencies in the range of 3.3-3.6 GHz, which are expected to be used for offering 5G services, the waves will travel around 100-150 metres.
· To expedite the roll out of 5G, telecom operators in the country will leverage street furniture such as poles, advertisement hoardings and bus shelters for deploying the Small Cells.
· They are usually deployed in dense urban areas such as downtown, stadiums, train stations, malls, and areas with high data capacity requirements and coverage.
Context – To expedite the roll out of 5G, telecom operators in the country will leverage street furniture such as poles, advertisement hoardings and bus shelters for deploying low power base stations called ‘Small Cells’ that will help bring the network closer to the consumers.

Question 4 of 5
4. Question
Consider the following statements regarding Nuclear Non-Proliferation Treaty (NPT)
- The right to peacefully use of nuclear technology is one of the Pillars of this treaty.
- Non-parties to the treaty are India, Israel, North Korea, Pakistan and South Sudan only.
Select the correct statement/s:
Correct
Solution (c)
Statement Analysis:
Statement 1 Statement 2 Correct Correct The NPT consists of a preamble and eleven articles. Although the concept of “pillars” is not expressed anywhere in the NPT, the treaty is nevertheless sometimes interpreted as a three-pillar system, with an implicit balance among them: 1. non-proliferation,
2. disarmament, and
3. the right to peacefully use nuclear technology.
As of August 2016, 191 states have become parties to the treaty, though North Korea, which acceded in 1985 but never came into compliance, announced its withdrawal from the NPT in 2003, following detonation of nuclear devices in violation of core obligations. Four UN member states have never accepted the NPT, three of which possess or are thought to possess nuclear weapons: India, Israel, and Pakistan. In addition, South Sudan, founded in 2011, has not joined. Context: Russia blocks final document at U.N. nuclear treaty conference
