0 UPSC EXAM ENGLISH QUIZ 26.12.2024 Daily Quiz 1 / 5 Q1. Consider the following statements: 1. Recently physicists revised the minimum mass of dark matter to 3.3 × 10-30 proton masses. 2. For decades scientists believed that the minimum mass was about 10-31 times the mass of a proton. Which of the above statement/statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Explanation: Recently physicists revised the minimum mass of dark matter to 2.3 × 10-30 proton masses. For decades scientists believed that the minimum mass was about 10-31 times the mass of a proton. In 1922, Dutch astronomer Jacobus Kapteyn concluded that "dark matter" (the first use of the term) had a density of 0.0003 solar masses per cubic light-year. Dark Matter Dark matter is a form of matter that is completely invisible, emitting no light or energy, making it undetectable by conventional sensors and detectors. Dark matter does not interact with electromagnetic forces, so it neither absorbs, reflects, nor emits light, making it difficult to detect. About 27% of the universe is made up of dark matter, which is six to one times more than visible matter, while visible matter is only 5%. Visible matter (baryonic matter) consists of subatomic particles such as protons, neutrons, electrons. 2 / 5 Q2. Consider the following statements: 1. Chairman of the Mission Governing Board of the National Quantum Mission announced that India plans to launch a quantum satellite within the next 2-3 years to enable quantum communications. 2. A quantum satellite is a communications satellite that uses quantum physics to secure its signals, making it highly resistant to interception. 3. Messages are encoded into a secret code using traditional encryption techniques, such as the Caesar cipher. Which of the statements given above is/are correct? 1 and 2 are correct 1 and 3 are correct 2 and 3 are correct All of the above Explanation: Chairman of the Mission Governing Board of the National Quantum Mission announced that India plans to launch a quantum satellite within the next 2-3 years to enable quantum communications. Quantum Satellite A quantum satellite is a communications satellite that uses quantum physics to secure its signals, making it highly resistant to interception. It uses quantum cryptography (a method that uses quantum mechanics to encrypt and transmit data), specifically quantum key distribution (QKD), to protect data by detecting eavesdropping during transmission. Quantum Cryptography Encryption Basics: Messages are encoded into a secret code using traditional encryption techniques, such as the Caesar cipher. Without the key, the message cannot be decoded. However, these methods are vulnerable to quantum computers, which can crack codes much faster than conventional supercomputers. 3 / 5 Q3. Consider the following statements: 1. Finance Minister chairs 55th meeting of Goods and Services Tax (GST) Council. 2. The GST Council has decided to increase the tax rate on sale of all used EVs from 22% to 18%, like non-electric vehicles. Which of the above statement/statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Explanation: Finance Minister chairs 55th meeting of Goods and Services Tax (GST) Council. Key decisions taken in 55th GST Council Meeting Used Electric Vehicles (EV): The GST Council has decided to increase the tax rate on sale of all used EVs from 12% to 18%, like non-electric vehicles. GST will apply only on margin value (difference between purchase and sale price, adjusting for depreciation, if claimed) in case of commercial sales. There will be no GST on individual-to-individual sales. Penal charges of banks: There will be no GST on penal charges levied by banks and non-banking financial companies (NBFCs) for loan tenure violations. Payment aggregators: Payment aggregators with payments of less than Rs 2,000 will be eligible for exemption. 4 / 5 Q4. Consider the following statements: 1. Northern Giant Hornet, also known as the Murder Hornet, has been successfully eradicated in the US. 2. The Northern Giant Hornet (Vespa mandarinia) is the world's largest hornet, up to 2 inches long. 3. A wasp is a type of insect belonging to the order Hymenoptera, which also includes bees and ants. Which of the statements given above is/are correct? 1 and 2 are correct 1 and 3 are correct 2 and 3 are correct All of the above Explanation: Northern Giant Hornet, also known as the Murder Hornet, has been successfully eradicated in the US. The Northern Giant Hornet (Vespa mandarinia) is the world's largest hornet, up to 2 inches long. A wasp is a type of insect belonging to the order Hymenoptera, which also includes bees and ants. It has a large head, solid yellow or orange color and black eyes. It is a species native to Asia and was first seen in Washington state near the Canadian border in 2019. It is a major threat to insects and native pollinators that can destroy an entire hive (housing of bees) in just 90 minutes. It can also kill people, as it is seven times more toxic than a bee and can sting multiple times. They usually build their nests in forested areas, often in underground cavities. 5 / 5 Q5. Consider the following statements: 1. 27th SIES Sri Chandrasekarendra Saraswati National Eminence Award presented to Jaishankar for leadership. 2. The South Indian Education Society (SIES) awarded External Affairs Minister S. Jaishankar the Sri Chandrasekarendra Saraswathi National Eminence Award for Public Leadership.
