Answer:
Confinement.
Strained.
Stifled.
Choke.
Explanation:
A sense of suffocation suggests a sense of 'forced' confinement, the need to get free, and be out and about. This is one theme in Anita Desai's "Games at Twilight" where the children were not allowed to go out in the open and play.
The four words that suggest a sense of suffocation are "confinement", "strained", "stifled", and "choke". These four words capture the feelings of the children who were eager to be out playing but instead were made to sit indoors. The author even stated that "the children . . . [felt] their lungs were stuffed with cotton wool and their noses with dust and if they didn't burst out into the light and see the sun and feel the air, they would choke."
