ANSWER TO MCQs
1. (a)
FYI:
— It is India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions. Hence, statement 1 is correct.
— As NASA explains on its website, X-rays have much higher energy and much shorter wavelengths, between 0.03 and 3 nanometers, so small that some x-rays are no bigger than a single atom of many elements. The physical temperature of an object determines the wavelength of the radiation it emits. The hotter the object, the shorter the wavelength of peak emission.
— X-rays come from objects that are millions of degrees Celsius — such as pulsars, galactic supernova remnants, and black holes.
— The spacecraft will carry two scientific payloads in a low earth orbit. Hence, statement 3 is not correct.
— Primary payload POLIX (Polarimeter Instrument in X-rays): It will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV photons of astronomical origin.
— XSPECT (X-ray Spectroscopy and Timing) payload: It will give spectroscopic information in the energy range of 0.8-15 keV. Hence, statement 2 is not correct.
Therefore, option (a) is the correct answer.

2. (c)
FYI:
— The year 2023 marks the first major conference of the United Nations (UN) dedicated to water since 1977. Hence, statement 1 is correct.
— According to the report, 26 per cent of the world’s population doesn’t have access to safe drinking water and 46 per cent lack access to basic sanitation. Hence, statement 2 is correct.
— The UN World Water Development Report 2023 painted a stark picture of the huge gap that needs to be filled to meet UN goals to ensure all people have access to clean water and sanitation by 2030.
— The UN 2023 Water Conference focuses on progress towards water- and sanitation-related goals, coinciding with the mid-term comprehensive review of the International Decade for Action, ‘Water for Sustainable Development 2018–2028’. Hence, statement 3 is correct.
— Sustainable Development Goal 6 (SDG 6) is to ensure the availability and sustainable management of water and sanitation for all by 2030.
Therefore, option (c) is the correct answer.

3. (d)
FYI:
— Trindade Island is one of the world’s most important conservation spots for green turtles, or Chelonia mydas, with thousands arriving each year to lay their eggs. The island is located in South Atlantic Ocean.
— The island has fascinated scientists with the discovery of plastic rocks. This melted plastic has become intertwined with rocks on the island, located 1,140 km (708 miles) from the southeastern state of Espirito Santo.
— The only human inhabitants on Trindade are members of the Brazilian navy, which maintains a base on the island and protects the nesting turtles.
Therefore, option (d) is the correct answer.
4. (b)
FYI:
— The DNA profiling of 270 of the 2,675 captive elephants in the country has been completed with the 30-year celebration of ‘Project Elephant’.
— The DNA profiling of elephants will act as the ‘Adhaar card of captive elephants. The process is being carried out in collaboration with the Wildlife Institute of India.
— The captive elephants had earlier been chipped electronically, but the method was not a success. Unlike Project Tiger, the Project Elephant looks at the welfare and health of captive elephants as well.
— India is home to 20% of the global captive Asian elephant population. Assam has the second largest wild elephant population in India. It also has a large number of captive elephants. Hence, statement 1 is correct and statement 3 is not correct.
— Project Elephant was launched in 1992 as a Centrally-sponsored scheme with an aim to protect elephants and improve its habitat and corridors, reduce human-elephant conflict and ensure their welfare. Hence, statement 2 is correct.
Therefore, option (b) is the correct answer.
