Designer: Any garden and adjoining living room that are separated from one another by sliding glass doors can visually merge into a single space. If the sliding doors are open, as may happen in summer, this effect will be created if it does not already exist and intensified if it does. The effect remains quite strong during colder months if the garden is well coordinated with the room and contributes strong visual interest of its own.
The designer's statements, if true, most strongly support which one of the following?
=> Firstly this is a inference question
Lets says Effect = merging
Summer : Doors open leads to effect
Winter : garden coordination and visual interest leads to effect (2 things not any one)
(A) a garden separated from an adjoining living room by closed sliding glass doors cannot be well coordinated with the room unless the garden contributes strong visual interest => These 2 conditions are mentioned in the winter but there is no link between them provided - INCOORECT
(B) In cold weather, a garden and an adjoining living room separated from one another by sliding glass doors will not visually merge into a single space unless the garden is well coordinated with the room => There is a second condition that is required i.e garden leads Visual interest of its own, so this only Half true - INCORRECT
(C) A garden and an adjoining living room separated by sliding glass doors cannot visually merge in summer unless the doors are open => Doors open leads to effect, but we are not given that its the only one way to lead to effect - INCORRECT
(D) A garden can visually merge with an adjoining living room into a single space even if the garden does not contribute strong visual interest of its own => Firstly see the word "can" that means there is a possibility; and the effect is possible during summers by just doors open - CORRECT
(E) Except in summer, opening the sliding glass doors that separate a garden from an adjoining living room does not intensify the effect of the garden and room visually merging into a single space => For winters its given the effect remains quite strong during winters, also we are not given that its the only condition (same reason as C) - INCORRECT
I got marked the incorrect option, took me time to reanalyse, hope this helps others.
