ANSWERS TO THE MCQs
1. (c)
FYI:
— The CSIR-National Chemical Laboratory (NCL) in Pune has efficiently demonstrated the operations of a pilot plant able to manufacturing Bisphenol-A, a key uncooked materials with excessive demand for manufacturing engineering plastics globally.
— The materials has wide-scale purposes as coating materials for meals and beverage cans within the packaging trade, in electronics and vehicle parts, and for the general manufacture of engineering plastics.
— However, increased traces of Bisphenol-A have been present in milk bottles for infants and circumstances of it leaching by meals cans have additionally been reported.
Therefore, choice (c) is the proper reply.
2. (a)
FYI:
— The neutrinos had been detected over a span of a decade on the IceCube Neutrino Observatory at a U.S. scientific analysis station on the South Pole, utilizing greater than 5,000 sensors masking an space the scale of a small mountain.
— Neutrinos are electrically impartial, undisturbed by even the strongest magnetic subject, and barely work together with matter, incomes the nickname “ghost particle.” Hence, assertion 3 is just not appropriate.
— As neutrinos journey by house, they cross unimpeded by matter – stars, planets and, for that matter, folks.
— Neutrinos are produced by the identical sources as cosmic rays. Cosmic rays, as electrically charged particles, can’t be traced straight again to their supply as a result of sturdy magnetic fields in house alter their trajectory. The path from which neutrinos arrive factors straight again to their authentic supply. Hence, assertion 2 is appropriate.
— The neutrino is an elementary particle, that means they don’t seem to be made up of something smaller. They usually are not the building blocks of ‘stuff,’ like electrons and quarks are, however they’re created in nuclear processes. Hence, assertion 1 is just not appropriate.
Therefore, choice (a) is the proper reply.
3. (c)
FYI:
— Amami-Oshima Island, Tokunoshima Island, the Northern a part of Okinawa Island, and Iriomote Island embody 42,698 hectares of subtropical rainforests on 4 islands on a series positioned within the southwest of Japan.
— The serial web site types an arc on the boundary of the East China Sea and Philippine Sea whose highest level, Mount Yuwandake on Amami-Oshima Island, rises 694 metres above sea degree.
— These islands are influenced by the Kuroshio Current and a subtropical high-pressure system, the property has a heat and humid subtropical local weather and is roofed primarily with evergreen broadleaved subtropical rainforests.
Therefore, choice (c) is the proper reply.

4. (d)
FYI:
— The Russian-built floating nuclear energy plant, Akademik Lomonosov accomplished its 5,000-km journey alongside the Northern Sea Route, inflicting pleasure within the power sector.
— The Akademik Lomonosov is a first-of-its-kind floating nuclear energy station in-built St Petersburg, the Russian port metropolis on the Gulf of Finland.
— It was named after the 18th-century Russian scientist Mikhail Lomonosov, the 21,000-tonne floating plant is 144 m lengthy and 30 m large, and incorporates two nuclear reactors of 35 MW every.
— It is a small plant in comparison with typical land-based nuclear initiatives.
— It is run by the state-owned nuclear power company Rosatom, the Akademik Lomonosov is anticipated to have a working lifetime of 40 years.
Therefore, choice (d) is the proper reply.
5. (a)
FYI:
— A group of researchers from the Gandhinagar-based Gujarat Ecological Education and Research (GEER) Foundation has found a brand new species of saltwort known as Salsola Oppositifolia Desfontania.
— The species belongs to the household of Amaranthaceae.
— This species, earlier recognized from Italy, Northern Africa, Palestine, Spain and Western Sahara, has been reported for the primary time from India primarily based on the gathering produced from Khadir Bet, Kutch, Gujarat at 15.5-m altitude.

— According to the analysis paper, the GEER Foundation, the brand new plant species is a perennial, succulent shrub that may develop one to 2 metres tall and have a easy, cylindrical, woody base. It is never prostrate and in contrast to different species of Salsola, doesn’t have any hairs.
— Salsola oppositifolia Desfontania is the sixth species of Salsola genus to be found in India. Previously, Salsola kali, Salsola hatmanii, Salsola monoptera, Caroxylon imbricatum (Salsola baryosma) and Halogeton glomeratus (Salsola glomerata) had been recorded in India.
Therefore, choice (a) is the proper reply.
