Question : Select the most appropriate option to fill in the blank.
Sitting at the computer, I saw something large and dark fall past my______ vision, followed by a dull thwack.
Option 1: central
Option 2: external
Option 3: peripheral
Option 4: incidental
Correct Answer: peripheral
Solution : The correct choice is the third option.
The most appropriate option to fill in the blank is peripheral.
In this context, "peripheral vision" refers to the outer part of the visual field, which allows the speaker to perceive objects and movement outside of his direct line of sight.
Therefore, the complete sentence would be: "Sitting at the computer, I saw something large and dark fall past my peripheral vision, followed by a dull thwack."
