1 UPSC EXAM ENGLISH QUIZ 21.12.2024 Daily Quiz 1 / 5 Q1. Consider the following statements: 1. Researchers have presented a new method to measure the properties of black holes using the effect they have on the light flowing around them (light echo). 2. A black hole is an extremely dense object whose gravity is so strong that nothing, not even light, can escape from it. Which of the above statement/statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Explanation: Researchers have presented a new method to measure the properties of black holes using the effect they have on the light flowing around them (light echo). black hole A black hole is an extremely dense object whose gravity is so strong that nothing, not even light, can escape from it. It has no surface, like a planet or star. Additionally, it is a region of space where matter runs out of matter. This catastrophic collapse results in the concentration of a very large mass into an incredibly small area. Formation: A black hole is formed when a very massive star runs out of fuel and explodes, causing its core to collapse under its own weight, forming a black hole. The centre of a black hole is a gravitational singularity, a point where the general theory of relativity breaks down, i.e. where its predictions no longer apply. The powerful gravitational pull of a black hole emerges from the singularity 2 / 5 Q2. Consider the following statements: 1. Tabla player Ustad Zakir Hussain dies of idiopathic pulmonary fibrosis (IPF). 2. It is a chronic, progressive lung disease in which lung tissue becomes scarred (fibrosed), leading to irreversible loss of lung function. 3. Our lungs are made up of millions of air sacs called alveoli, through which oxygen and carbon dioxide are exchanged. 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: Tabla player Ustad Zakir Hussain dies of idiopathic pulmonary fibrosis (IPF). Idiopathic Pulmonary Fibrosis It is a chronic, progressive lung disease in which lung tissue becomes scarred (fibrosed), leading to irreversible loss of lung function. Our lungs are made up of millions of air sacs called alveoli, through which oxygen and carbon dioxide are exchanged. In IPF, the alveoli and surrounding tissue thicken and stiffen, reducing their elasticity, impeding oxygen exchange. Pulmonary fibrosis is an interstitial lung disease. 3 / 5 Q3. Consider the following statements: 1. According to the Ministry of Housing and Urban Affairs, India's electronic waste (e-waste) generation has increased by 73% over the last five years. 2.

This financing is intended to promote coastal preservation and boost community resilience in Maharashtra. ADB funding will contribute to the restoration and stabilisation of Maharashtra's coastline. ADB funding will also contribute to the protection of coastal populations' livelihoods. ADB will assist the Maharashtra Maritime Board in increasing its capability for shore management planning, including the development of a coastal infrastructure management unit. The initiative will help stakeholders build capacity in gender equality and social inclusion, coastal management, and livelihood activities. 5 / 5 Q5. Consider the following statements: 1. India’s coal imports declined 3.1% in FY 2024-25. 2. India imported 149.39 million tonnes (MT) of coal between April and October of FY 2024–25.

India’s imports in April and October of FY 2024–25 declined 3.1 percent from 154.17 MT during the same period in FY 2023–2024.
