Answer:
C) how loud the boys' laughter and movements are.
Step-by-step explanation:
In How I Learned English by Gregory Djanikian, the speaker had just moved from Egypt and was unable to use proper English which left him without friends. But at this one baseball game, he had wrongly exclaimed "Oh my shin, oh my shin", which was awkward for him for he did not know how the other boys would react to his use of the English words.
But when someone said "shin" again, he then realized that he has been accepted in the friend circle. All of them ended up laughing and tumbling on the ground, unable to control the "fit of laughter" that had apparently overtaken the boys.
The given description provides the readers with an image of how the reaction to the word "shin" led to the uproarious result in the field. The speaker states that "there was wild stamping of hands on the ground, kicking of feet" which led to him also getting the "fit of laughter" that had taken over the other boys.
