Hey AbdurRakib, let us try to break this question here.
Dorsey received a dining room set from his grandmother, who had stored the furniture in a storage facility for more than a year. When he sat in one of the chairs, however, the wicker seat buckled and split. Dorsey attributed the break to the damp and musty conditions in the storage locker, which had caused the seat to rot.
Which of the following, if true, casts the most serious doubt on Dorsey’s conclusion
Type: Weaken. Whenever the prompt says cast a doubt, it means we are tackling with a weaken question type.
Premise: Dorsey's furniture was kept in damp and musty conditions in the storage locker and Dorsey thinks this is the cause why the seat broke.
Analysis:Dorsey blames the damp and moist conditions of the storage locker as it caused the set to rot
A) The table, which was not made of wicker, did not appear to sustain any substantive damage.
This statement is out of context as the chair sustained the damage when Dorsey sat on the seatB) Dorsey broke through the seat of a brand-new identical chair that he bought to replace the broken one.
This is precisely what we are looking for. This shows that the reason why the seat broke was not the conditions of the storage.
The problem is Dorsey as s/he somehow manages to break any seat.C) The storage company had never received any complaints about rotted furniture in the past.
This again does not tell anything about the chair in contention, hence out of contextD) Dorsey keeps a lot of his old furniture in his basement, which is also musty and damp.
This again does not tell anything about the chair in contention, hence out of contextE) The furniture manufacturer refused to honor the chair’s warranty because it felt the chair had been treated poorly.
We are not concerned about the chair's warranty, but about the reason why the chair broke.
