21. 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?

(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.

(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.

(C) A garden and an adjoining living room
separated by sliding glass doors cannot visually
merge in summer unless the doors are open.

(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.

(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

Why D is the right answer?

Conclusion: Any garden and adjoining living room that
are separated from one another by sliding glass
doors can visually merge into a single space.

Premise:If the sliding doors are open, as may happen in
summer, this effect (can visually merge into a single space)will be created if it does not
already exist and intensified if it does .

Premise: The effect (can visually merge into a single space)remains quite strong during colder months if the
garden is well coordinated with the room and
contributes strong visual interest of its own.

在红色的三种情况下（3个if)，都会有can visually merge into a single space.

D) even if the garden does not contribute strong visual interest of its own =不是第三个if,

但可以认为是
第一或第二个if中的一个或两个，这两个都可以推出can visually merge into a single spa

Thank you. From your explanation, can I conclude that based on If A + B, then C,
If A (without B), then C is also correct
does not seem to be right
I guess I am still confused

The essence of the stimulus is saying that there are two sets of sufficient conditions爐hat爓ould爉ake a garden adjoining a living room that are separated from one another by sliding glass doors to visually merge into a single space.

The two sufficient conditions are: 1. openning the door in summer; 2. in colder months: a garden is well coordinated with the room and
contributes strong visual interest of its own.

The credited option D boils down to: a necessary condition could occur without its sufficient conditions being met.
