Final answer:
Formalist and Hypocrisy in 'The Pilgrim's Progress' are headed to Mount Zion to maintain appearances of righteousness, embodying the vice of hypocrisy, rather than seeking true spiritual change.
Step-by-step explanation:
The characters Formalist and Hypocrisy in the allegorical novel The Pilgrim's Progress by John Bunyan are headed to Mount Zion with superficial intentions rather than genuine faith. While the desired destination of Mount Zion represents spiritual enlightenment and salvation, these characters are depicted as taking the journey for appearances and outward show, rather than true internal spiritual change. Therefore, the correct answer is not for worldly gain, spiritual enlightenment, or eternal rest, but rather to maintain an appearance of righteousness, which can be classified under hypocrisy. This behavior aligns with their symbolic names and their roles in the story as examples of people who undertake religious journeys or practices without the inner conversion that the pilgrimage is meant to represent.
