Four sentences that are a part of paragraph are given below; the sentences may or may not
be in the right order; create the sequence that forms a coherent paragraph.
(i) In the central nervous systems of other animal species, such a comprehensive regeneration of neurons has not yet been proven beyond doubt.
(ii) 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.
(iii) They studied the Mauthner cells, which are solely responsible for the escape behaviour of the fish, and previously regarded as incapable of regeneration.
(iv) However, their ability to regenerate crucially depends on the location of the injury.

The passage begins with Option 2, which says "Researchers ... found ... recovery in neurons ...". The pronoun "they" refers to the scientists in the Options 3 and 2. Thus 23 forms a pair. Option 4 has the pronoun "their potential", which refers to the recovery ability of "Mautner cells". Next do the Options 3 and 4 a pair structure. Option1 has no space other than the end. After this Options 2,3,4 and 1 structures make the correct arrangement.
