Name the shared goal, then compare the same feature in both texts: materials, steps, or limits. Support each difference with a detail from each plan.
Worked example
If Plan A sorts books by author and Plan B sorts them by topic, both organize books, but their sorting rules differ. Neither detail tells which plan costs more.
Two Book Exchange Plans
Plan A: A school club will hold a book exchange on one Saturday. Volunteers will sort donated books by reading level. Visitors can take one book for each book they bring. No books are sold. Plan B: A library will keep an exchange shelf open during its regular hours. Books will be sorted by topic. Visitors may take one book even if they do not bring one. A volunteer will check the shelf each afternoon.
