CAPF AC 2021 Q117: Current Affairs – National Events & Institutions

CAPF AC 2021, Paper I (General Ability and Intelligence) · Current Affairs

Match List I with List II and select the correct answer using the code given below the Lists: | List I (Variant of COVID-19) | List II (First identified in) | |---|---| | A. Alpha | 1. India | | B. Beta | 2. Brazil | | C. Gamma | 3. Britain | | D. Delta | 4. South Africa | Code:

(a) A-3, B-4, C-2, D-1
(b) A-1, B-2, C-4, D-3
(c) A-1, B-4, C-2, D-3
(d) A-3, B-2, C-4, D-1

Answer: (a) A-3, B-4, C-2, D-1

Explanation

COVID-19 variants and where they were first found

How to think: on 31 May 2021 the WHO gave Greek letter names to the variants.

The letters were given in the order in which the variants were listed.

Variant	Scientific name	First identified in
A. Alpha	B.1.1.7	Britain (3)
B. Beta	B.1.351	South Africa (4)
C. Gamma	P.1	Brazil (2)
D. Delta	B.1.617.2	India (1)

So the code is A-3, B-4, C-2, D-1.

Why Greek letters: the names are easy to say and they avoid blaming a country for a variant.

Later: Omicron (B.1.1.529) was reported from South Africa and Botswana in November 2021.

Answer: (a) A-3, B-4, C-2, D-1.

Why each option is right or wrong

(a) CORRECT. Alpha: Britain, Beta: South Africa, Gamma: Brazil, Delta: India.
(b) Incorrect. It links Alpha with India and Delta with Britain, the reverse of the facts.
(c) Incorrect. Beta and Gamma are right here, but Alpha and Delta are swapped.
(d) Incorrect. Alpha and Delta are right here, but Beta and Gamma are swapped.

Key point

WHO labels (31 May 2021): Alpha (UK), Beta (South Africa), Gamma (Brazil), Delta (India), later Omicron (South Africa and Botswana, November 2021). Delta drove India's second wave in 2021.

Remember

Alpha UK, Beta South Africa, Gamma Brazil, Delta India.

Common mistakes

Swapping Alpha and Delta, thinking India's variant came first.
Mixing up Beta (South Africa) with Gamma (Brazil).
Using the country names for variants, which the WHO asked everyone to avoid.

Exam tip

Educated guess: Delta is the one everyone in India remembers from the second wave, so D-1 is fixed. That leaves (a) and (c). Alpha was the so-called UK variant of late 2020, which gives (a).
