QUIZ – 2020: Insights Current Affairs Quiz, 3 May 2021

Solution: c)

Newly published results of an international experiment hint at the possibility of new physics governing the laws of nature, scientists say. The results of the experiment, which studied a subatomic particle called the muon, do not match the predictions of the Standard Model, on which all particle physics is based, and instead reconfirm a discrepancy that had been detected in an experiment 20 years previously.

The muon g-2 experiment:

• Fermilab, which houses the American particle accelerator, has released the first results from its ‘muon g-2’ experiment.
• These results spotlight the anomalous behaviour of the elementary particle called the muon. The muon, a heavier cousin of the electron, is expected to have a value of 2 for its magnetic moment, labelled ‘g’.
• However, the muon exists not in isolation but embedded in a sea where particles are popping out and vanishing every instant due to quantum effects.
• So, its g value is altered by its interactions with these short-lived excitations.

Solution: d)

• The first Lok Adalat camp was organised in Gujarat in 1982 as a voluntary and conciliatory agency without any statutory backing for its decisions.
• In view of its growing popularity over time, it was given statutory status under the Legal Services Authorities Act, 1987. The Act makes the provisions relating to the organisation and functioning of the Lok Adalats.
• The term ‘Lok Adalat’ means ‘People’s Court’ and is based on Gandhian principles.
• It is one of the components of the Alternative Dispute Resolution (ADR) system and delivers informal, cheap and expeditious justice to the common people.

Solution: b)

Feni River is a river in southeastern Bangladesh and Tripura. It is a trans-boundary river with an ongoing dispute about water rights. The Feni River originates in South Tripura district and flows through Sabroom town and then enters Bangladesh. It discharges into Bay of Bengal.

Solution: b)

A registered party is recognised as a national party only if it fulfils any one of the three conditions listed below:

1. A party should win 2% of seats in the Lok sabha from at least three different states.[8]
2. At a general election to Lok Sabha or Legislative Assembly, the party polls 6% of votes in any four or more states and in addition it wins four Lok Sabha seats.
3. A party gets recognition as a state party in four states.
4. A party gets at least 8% of total valid votes polled in 4 or more states ( with or without any seats)

Solution: d)

Toxins in water produced by cyanobacteria killed more than 300 elephants in Botswana.

Cyanobacteria are microscopic organisms common in water and sometimes found in soil. Not all produce toxins but scientists say toxic ones are occurring more frequently as climate change drives up global temperatures.

Some cyanobacterial blooms can harm people and animals and scientists are concerned about their potential impact as climate change leads to warmer water temperatures, which many cyanobacteria prefer.
