Final answer:
The line "He thinks about it for a year" from "The Sloth" contains five iambic feet, making it an example of iambic pentameter.
Step-by-step explanation:
The line from "The Sloth," He thinks about it for a year, contains five iambic feet. An iambic foot, commonly found in English poetry, consists of an unstressed syllable followed by a stressed one (x /). Considering this, the line breaks down into iambs as follows: He thinks | about it | for a year. As it consists of five sets of iambs, this line is also an example of iambic pentameter, a style of poetic meter frequently used by poets such as Shakespeare in his works, including the well-known line "Shall I compare thee to a summer's day?"
