0 UPSC EXAM ENGLISH QUIZ 14.08.2024 Daily Quiz 1 / 5 Q1. Consider the following statements: 1. NITI Aayog has laid down a comprehensive roadmap to promote seaweed cultivation in India in its report published titled “Strategy for the development of Seaweed Value Chain”. 2. This includes steps for research, investment, training, infrastructure development, and market promotion to increase seaweed production, which can benefit the environment, economy, and local communities. Which of the above statement/statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Explanation: NITI Aayog has laid down a comprehensive roadmap to promote seaweed cultivation in India in its report published titled “Strategy for the development of Seaweed Value Chain”. This includes steps for research, investment, training, infrastructure development, and market promotion to increase seaweed production, which can benefit the environment, economy, and local communities. Seaweeds They are the primitive, marine non-flowering algae without root, stem and leaves and play a major role inmarine ecosystems. Large seaweeds form dense underwater forests known as kelp forests, which act as underwater nurseriesfor fish, snails and sea urchins. Some species of seaweeds are Gelidiella acerosa, Gracilaria edulis, Gracilaria crassa, Gracilaria verrucosa,Sargassum spp. and Turbinaria spp. It is classified into green (Chlorophyta), brown (Phaeophyta), and red (Rhodophyta) groups. 2 / 5 Q2. Consider the following statements: 1. For the second time in the last two years, Antarctica is experiencing record-breaking heat during the peak winter season. • The polar vortex (also known as polar pig) is a large area of low pressure and cold air surrounding both of the Earth’s poles. 2. The term "vortex" refers to the counterclockwise flow of air that helps keep the colder air near the Poles. 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: For the second time in the last two years, Antarctica is experiencing record-breaking heat during the peak winter season. The heatweb has caused terrestrial temperatures to average 10 degrees Celsius above normal since mid-July, and sometimes as much as 28 degrees higher. Weakening of the Polar Vortex The polar vortex (also known as polar pig) is a large area of low pressure and cold air surrounding both of the Earth’s poles. The term "vortex" refers to the counterclockwise flow of air that helps keep the colder air near the Poles. It always exists near the poles, but weakens in summer and strengthens in winter. Higher temperatures and powerful atmospheric waves (periodic disturbances in the fields of atmospheric variables) disrupted the vortex. This allowed cold air to escape and warm air from above to descend. The arrival of this warm air led to a rise in temperatures in the region. 3 / 5 Q3. Consider the following statements: 1. Scientists have drilled the deepest ever into rock from Earth's mantle using the marine drilling vessel JOIDES Resolution. 2. The drilling went 3,160 feet (1,268 meters) below the Atlantic seafloor. This drilling has produced a large sample of rock from the mantle, the most voluminous layer of the Earth. Which of the above statement/statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Explanation: Scientists have drilled the deepest ever into rock from Earth's mantle using the marine drilling vessel JOIDES Resolution. The drilling went 4,160 feet (1,268 meters) below the Atlantic seafloor. This drilling has produced a large sample of rock from the mantle, the most voluminous layer of the Earth. This cylindrical core sample will provide information about the structure and chemical reactions of the upper part of the mantle. The rocks of the mantle layer are at such a depth that they are difficult to obtain. However, there are some places on the sea floor where these mantle rocks are visible. One such place is the Atlantis Massif, an underwater mound or mountain where mantle rock is exposed on the ocean floor. 4 / 5 Q4. Consider the following statements: 1. SJVN Green Energy Limited (SGEL) commissioned the 50 MW Omkareshwar Floating Solar Project. 2. SJVN Limited is a Mini Ratna Schedule 'A' Central Public Sector Undertaking (CPSU) under the Ministry of Power, Government of India. 3. The Omkareshwar Floating Solar Park is located in Khandwa district of Madhya Pradesh. 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: SJVN Green Energy Limited (SGEL) commissioned the 90 MW Omkareshwar Floating Solar Project. SJVN Limited is a Mini Ratna Schedule 'A' Central Public Sector Undertaking (CPSU) under the Ministry of Power, Government of India. Omkareshwar Floating Solar Project The Omkareshwar Floating Solar Park is located in Khandwa district of Madhya Pradesh. The park is India's largest floating solar park. The project aims to significantly reduce carbon emissions by 2.3 lakh tonnes of CO2, thereby meeting India's goal of achieving net-zero emissions by the year 2070. It will also help in water conservation by reducing water evaporation. India's installed solar power capacity has grown significantly, reaching 85.47 GW by June 2024. As of May 2024, the total installed capacity of renewable energy sources is 195.01 GW, comprising 46.65 GW of wind power, 10.35 GW of biomass/cogeneration, 5 GW of small hydro, 0.59 GW of waste-to-energy and 46.92 GW of large hydro. 5 / 5 Q5. Consider the following statements: 1. Microorganisms that thrive in extreme heat environments such as microwave ovens were studied to understand their evolutionary adaptations. 2. The dominant bacteria belonged to the Bacillus, Micrococcus and Staphylococcus genera, which commonly live on human skin and surfaces that people frequently touch. Which of the above statement/statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Explanation: Microorganisms that thrive in extreme heat environments such as microwave ovens were studied to understand their evolutionary adaptations. Key findings The dominant bacteria belonged to the Bacillus, Micrococcus and Staphylococcus genera, which commonly live on human skin and surfaces that people frequently touch. Some strains of bacteria associated with foodborne illnesses, including Klebsiella and Brevundimonas, also grew in household microwaves. Laboratory microwave ovens had the greatest genetic diversity (variation in genes within a species) of bacteria. Microwave heating uses electromagnetic waves (300 megahertz to 300 gigahertz) to generate heat and inactivate most microorganisms in food.
