Question

The four sentences (labelled 1, 2, 3 and 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. Fish skin collagen has excellent thermo-stability and tensile strength making it ideal for use as bandage
that adheres to the skin and adjusts to body movements.
2. Collagen, one of the main structural proteins in connective tissues in the human body, is well known for
promoting skin regeneration.
3. Fish skin swims in here as diseases and bacteria that affect fish are different from most human pathogens.
4. The risk of introducing disease agents into other species through the use of pig and cow collagen proteins
for wound healing has inhibited its broader applications in the medical field

• A. 2413
• B. 2431
• C. 1342
• D. 1432

Answer 1

The Correct Option is B

This is a much more doable question. Sentence 3 says ‘fish skin swims in here…’. To swim in here means to come and fill a gap or fulfil a role. 4 says that because there are risks in collagen proteins derived from pigs and cows, they cannot be used in the medial field. 3 says fish skin swims in here and fills the gap. Thus 43 form a pair. 2 is the opening sentence because it discusses collagen in general talks about its function. Both 3 and 1 talk about fish collagen and form a pair. The right sequence is 2431.
