The passage is about a new form of state “Bose-Einstein condensate”. In the latter part of the passage, the word ‘atoms’ has been mentioned. Hence, option C is the correct answer.

The idiom “within a hair of something” means extremely close to doing, achieving, or obtaining something, typically having failed by a very narrow margin.

Hence, option D is the correct answer.

The first sentence of the passage talks about how a “Bose-Einstein condensate” is formed (by cooling it to an absolute zero temperature). Hence, option A, i.e. temperature, is the correct answer.

The infinitive construction is ‘to + base form of the verb’. Hence, option B is the correct answer.

We use “as if” and “as though” when we are giving a possible explanation for something or saying that something appears to be the case when it is not. The group of atoms starts behaving like a single atom (but they are not a single atom). Therefore, “were” will be used in the blank to express an unreal or hypothetical condition.

Hence, option B is the correct answer.

In the blank, we either can fill an article or a possessive pronoun, because “31st goal” either is in possession of the subject or belong to the tournament. Now, as the sentence is indicating towards a definite goal i.e. “31st goal”, we must use the definite article ‘the’ or the possessive pronoun ‘his’ to imply that it is the “31st goal” of Messi’s career. As ‘the’ is not in the option ‘his’ will be the perfect fit.

Hence, option C is the correct answer.

Clearly, we need to complete the infinitive here, that will work as the object of the verb “is looking”. The structure of the infinitive is “To + V1”. Thus, ‘Lift’ is the correct verb to use here.

Hence, option A is the correct answer.

Barcelona is a football club. When we speak about making our career or profession, we particularly use the preposition ‘with’ before the organization we want to get into.

E.g. I am looking for starting my corporate career with a multinational company.

Hence, option B is the correct answer.

The sentence is in active voice and the verb is in V3 (past participle) form. So the sentence is in the perfect tense and we need a “have” verb to fill in the blank. As the subject “Treble-chasing Bayerns” is a plural verb, ‘have’ is the best verb to use.

Hence, option C is the correct answer.

The sentence is in the present tense. So, the verb, which is required in the blank, should also be a present verb. Also, as the subject “coronavirus lockdown” is singular, the verb must have an added ‘-s’. The verb “restarts” is also apt contextually.

Hence, option A is the correct answer.
