Question

which sentence or sentences have correct parallel structure?
during our trip to washington, d.c., we will visit the white house, tour the u.s. capitol, and maybe even meet with our representative in congress.
during our trip to washington, d.c., well visit the white house, well tour the u.s. capitol, and maybe even meet with our representative in congress.

Explanation:

To determine correct parallel structure, we check if the verb phrases are in the same form. In the first sentence, "visit", "tour", and "meet" are all base - form verbs (in the future - tense context with "will"), creating parallelism. In the second sentence, the first two clauses have the subject "we'll" but the third part "maybe even meet..." lacks the subject "we'll" in the same way, breaking parallelism. So only the first sentence has correct parallel structure.

Answer:

During our trip to Washington, D.C., we will visit the White House, tour the U.S. Capitol, and maybe even meet with our representative in Congress.
