Recent research conducted in City X shows that children who are not fastened by safety belts are more likely to be injured in the case of a car accident than children who are fastened by safety belts. Belted-in children in the passenger seat are more likely to be injured than belted-in children in the back seat although safety belts always lower the chances of being injured.
It is, therefore, recommended that children always be seated in the back seat and have their safety belts fastened.A. Children who sit in the passenger seat tend to distract the driver's attention, thus increasing the likelihood of a car accident.
Incorrect
The conclusion is concerned with the children who sit at the back seat and not in the passenger seat, hence this is invalid to the argument.B. Children who are seated in the back seat usually unfasten their seat belts.
CorrectAs this weakens the conclusion and talks about the children sitting in the back seat.C. Specially designed safety seats for children also help prevent injury in the case of an accident.
Incorrect
The argument is about seatbelts and front/back seat for the children, the point of safety seats is irrelevant to say the least. If anything this will act as a strengthener rather than a weakener.D. City X has a higher percentage of car accidents involving children than any other part of the country.
Incorrect
Irrelevant as it talks about a comparisons between City X and other parts of the country which is not the basis of this questions statementE. Of all the cases included in the research, 20% of the children who were seated in the back seat and had their seat belts fastened sustained minor injuries as a result of a car accident.
Incorrect
We can not conclude anything from the 20% mention in the option choice here as there is nothing to compare it with, saying that this choice acts as a strengthener rather than a weakenerHope this was helpful, happy learning!!
