Science and Technology has remained one of the difficult sections of IAS Prelims Exam. For the preparation of IAS Prelims Exam, here we have provided important Science and Technology quiz based on the recent events of national and international importance.
1. Recently India has completed its nuclear triad by inducting which of the following submarine into service?
a. INS Vikrant
b. INS Shishumar
c. INS Arihant
d. INS Aridhaman
Recently, India has completed its nuclear chord by inducting country's first indigenously-constructed nuclear submarine INS Arihant into service. INS Arihant was formally commissioned by Navy Chief Admiral Sunil Lanba in August 2016.
INS Arihant is the lead ship of India's Arihant class of nuclear-powered ballistic missile submarines. The 6000 tonne vessel was built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in the port city of Visakhapatnam.
2. The Scientists unveiled fossils from a new species of giant, long-necked dinosaur unearthed in which of the following country?
In northeast Australia, the scientists unveiled fossils from a new species of giant, long-necked dinosaur. They are speculating that its ancestors had trekked across Antarctica some 105 million years ago.
At least 14 metres from head-to-tail, Savannasaurus elliottorum was a plant-chomping, barrel-chested member of the sauropod group, which includes the largest land animals to ever have roamed the planet.
3. Consider the following statements regarding the Air Quality Index (AQI):
I. AQI is calculated based on both particle and gaseous pollutants in the air, including PM10 and PM2.5 (particles with diameter less than 10 and 2.5 micro metres), NO2, SO2, NH3, lead, CO and O3.
II. PMs are the pollutants responsible for respiratory and cardiovascular diseases, while Nitrogen Dioxide (NO2) and others cause lung diseases, lung tissue damage, reduction of lung function and eye-related issues.
Which of the following statement(s) is/are correct?
a. Only I
b. Only II
c. Both I and II
d. Neither I nor II
An air quality index is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects.
PMs are the pollutants responsible for respiratory and cardiovascular diseases, while Nitrogen Dioxide (NO2) and others cause lung diseases, lung tissue damage, reduction of lung function and eye-related issues.
4. Recently, India has established a Joint Committee under the Scientific and Technological Cooperation Agreement re-launch of cooperation in the sectors of science, technology and innovation in which of the following countries?
Recently, India has established a Joint Committee established under the Scientific and Technological Cooperation Agreement re-launch of cooperation in the sectors of science, technology and innovation. The original agreement was signed between Italy and India in 2003.
The Indian delegation led by Secretary to the Government of India, Department of Science and Technology, Prof. Ashutosh Sharma, while the Italian delegation was led by Vincenzo De Luca, Director General for Cultural and Economic Promotion and Innovation of the Ministry of Foreign Affairs and International Cooperation.
5. Which of the following has moved closer to establish its permanent space station by 2022 as it launched a spacecraft carrying two astronauts, in its longest-ever manned space mission?
Recently China has moved closer to establish its permanent space station by 2022 as it launched a spacecraft carrying two astronauts, in its longest-ever manned space mission who would later join its second experimental space lab orbiting the Earth.
China, which conducted its first manned space mission in 2003, is putting in billions into its space programme in a bid to catch up with the US and Europe. It also plans to launch its maiden Mars mission in 2020 to match India and others.
6. Antiretroviral therapy (ART) is the combination of several antiretroviral medicines used to treat which of the following disease?
d. Swine Flue
Antiretroviral therapy (ART) is the combination of several antiretroviral medicines used to slow the rate at which HIV makes copies of itself (multiplies) in the body. A combination of three or more antiretroviral medicines is more effective than using just one medicine (monotherapy) to treat HIV.
