Options (A), (C), and (D) cannot be the correct answer because 'highest', 'higher' and 'more high' ('more high' is an incorrect form of comparison - higher is used instead) are degrees of comparison that are to be used when the subject in a sentence is being compared to something else.

Since the 'rubber swimsuits' aren't being compared to anything in that sentence, these three options cannot be used.

The first sentence of the passage mentions that the topic is of rubber swimsuits. This inherently means that they have to do with swimming.

Option (A) cannot be the answer as 'fish' do not wear rubber swimsuits.

Option (B) cannot be the answer as 'scientists' have no use for rubber swimsuits.

Option (C) cannot be the answer as 'person' is a very generic term and could be used for an individual that may or may not need a swimsuit.

Option (A) cannot be the answer as 'lycra' is not a garment, it is a material that garments are made of.

Option (B) cannot be the answer as 'lycra' is not an object - this is a very generic term - it is more specifically a material.

Option (D) cannot be the answer as 'lycra' is not matter - we are not being very specific if we use the word 'matter' as all objects are made of matter.

Option (A) is the answer as 'faster' means able to move or act at great speed.

Option (B) cannot be the answer as 'speedy' is an adjective that is used in reference to moving or 'swimming' in general.

Option (C) cannot be the correct answer as 'hasty' is no referred to in terms of 'swimming', is usually used to refer to going from one place to another in a hurry.

Option (D) cannot be the answer as 'quick' is not a comparative term and based on the structure of the sentence, the blank requires a comparative term.

Option (B) 'rubber' cannot be the answer as the sentence refers to protection from something, and the rubber swimsuit cannot be used for protection against the rubber. 

Option (C) 'friction' cannot be the answer as 'friction' is not something that can be soaked up.

Option (D) 'lycra' cannot be the answer as the purpose of a swimsuit is to protect a person from the water that they are swimming in and a swimsuit made of lycra will not be used for protection against lycra.
