Para JumblesVerbal AbilityType in the answer (TITA)Medium

The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:

1. In the central nervous systems of other animal species, such a comprehensive regeneration of neurons has not yet been proven beyond doubt.

2. Biologists from the University of Bayreuth have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish.

3. They studied the Mauthner cells, which are solely responsible for the escape behaviour of the fish, and previously regarded as incapable of regeneration.

4. However, their ability to regenerate crucially depends on the location of the injury.

Answer & solution

Answer: 2341

Sentence 2 opens the paragraph: it introduces the biologists at Bayreuth and their discovery in zebrafish.

Sentence 3 follows: 'They' refers to the biologists, and it names the cells studied – the Mauthner cells.

Sentence 4 comes next: 'However, their ability to regenerate' adds a condition on the regeneration of these cells.

Sentence 1 ends the paragraph: it compares with 'other animal species', where 'such a comprehensive regeneration' has not been proven. 'Such' needs the regeneration to be described first.

Shortcut: 'They' in 3 needs 2 before it, and 'such' in 1 shows it comes late. 2-3 is a mandatory pair.

Hence, the answer is 2341.
