The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.

Question 1 of 5

1. Question

Consider the following statements about Direct Seeded Rice (DSR)

It is the process of growing rice from seeds sown in the ground as opposed to transplanting seedlings from a nursery.
Unlike puddled transplanted rice (PTR) method, DSR delivers faster planting and maturing, conserves scarce resources like water and labour.

Choose the correct statements:

a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2

Correct

Solution (c)

Statement Analysis

Statement 1

Statement 2

Correct

· Direct Seeded Rice (DSR) describes the process of growing rice from seeds sown in the ground as opposed to transplanting seedlings from a nursery.

· DSR is seen to be most productive, environmentally friendly and financially feasible rice production systems used today.

· Since 1950s, it has been recognised as the primary way of growing rice in countries.

· Pusa Basmati 1121 (PB 1121) is a landmark Basmati rice variety having Basmati quality traits intro-gressed from traditional Basmati varieties.

· Pusa Basmati 1509 Early maturing, reduced height, non-lodging and non-shattering variety.

· It matures in 115 days which is 30 days early to Pusa Basmati 112.

· It saves 33% water.

· Unlike puddled transplanted rice (PTR) method, DSR delivers faster planting and maturing, conserves scarce resources like water and labour.

· It is more conducive to mechanization, and reduces emissions of greenhouse gases that contribute to climate change.

· Mechanized DSR also creates avenues for employment through new service provisions and is less labour intensive and free from drudgery, hence more attractive to youth and women farmers.

Context: The Indian Council of Agricultural Research has commercialised herbicide-tolerant basmati rice varieties, claiming they can control weeds in rice crops while also promoting water-saving direct seeded rice.

Question 2 of 5

2. Question

Consider the following statements about Parengyodontium album

It is a marine bacteria that can break down plastic polyethene (PE), the most common plastic in the ocean.
In this bioremediation process, the PE-derived carbon is converted into the biomass of P. album, serving as its energy source.

Choose the incorrect statements:

a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2

Correct

Solution (a)

Statement Analysis

Statement 1

Statement 2

Correct

· It is a marine fungus that can break down plastic polyethene (PE), the most common plastic in the ocean.

· It was discovered by Marine microbiologists from the Royal Netherlands Institute for Sea Research (NIOZ).

· Considering fungi as the ‘masters of degradation’ that they utilise a plethora of digestive enzymes for plastic degradation, researchers expect that there could be more plastic-degrading fungi in the deeper parts of the ocean.

· In this bioremediation process, the PE-derived carbon is converted into the fungal biomass of P. album, serving as its energy source.

· Initial photodegradation of PE by UV sunlight is crucial for this process. It makes the fungus useful to degrade the floating oceanic plastic litter.

· Humans produce over 400 billion kilograms of plastic annually, much of which ends up in the ocean.

Context: A marine fungus called Parengyodontium album has been discovered to break down plastic polyethene (PE) in the ocean.

3. Question

Consider the following statements about Dnieper River

It is the second longest river in Europe after the Volga.
It runs through western Russia, Belarus, and Ukraine before emptying into the Black Sea.
The city of Kiev and Zaporizhia of Ukraine are located on the banks of Dnieper River.

How many of the statements given above are correct?

a) Only one
b) Only two
c) All three
d) None of the above

Correct

Solution (b)

Statement Analysis

Statement 1

Statement 2

Statement 3

Incorrect

Correct

· It is the fourth-longest river in Europe (after the Volga, the Danube, and the Ural).

· In Russian, the river’s name is Dnepr. In Ukrainian, it is Dnipro, and in Belarusian, it is Dnyapro.

· Located in Eastern Europe, the Dnieper River and its tributaries drain much of Belarus and Ukraine.

· It originates in Russia, in the low Valday Hills west of Moscow.

· It runs a total length of 1,368 miles through western Russia, Belarus, and Ukraine before emptying into the Black Sea.

· Approximately 300 miles of the waterway is located in Russia, 430 miles are in Belarus, and 680 miles are within Ukraine.

· It passes through numerous urban centers such as the Russian cities of Smolensk and Dorogobuzh, as well as Mogilev in Belarus and Kiev, Cherkasy, Dnipro, and Zaporizhia in Ukraine.

· Tributaries: It has as many as 32,000 tributaries, including the Sozh, Desna, Trubizh, Bilozerka, Drut, Berezina, and Prypiat Rivers.

Context: Russian missile attack on the central city of Dnipro injured seven people, including two children, and damaged civilian infrastructure recently.
