Question 21 : 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.

Explanatory Answer

Sentence 2 is the best opening sentence. Sentence 3 begins with the pronoun ˜they™ (which can only refer to the biologists, the subject of sentence 1) and describes what was studied. So, 3 follows 2. The best place for sentence 4 in the paragraph is immediately after 3. Sentence 1, which talks about other species, must be the last sentence of the paragraph. So, 2341 is the correct order.

The answer is '2341'
