Directions: Each of the following sentences has a blank space and four choices…

An indirect (embedded) question — one that follows a frame like "Do you know...?" — keeps normal statement word order inside the blank: wh-word + subject + verb, with no subject-auxiliary inversion, and the preposition either stays stranded at the end or (more formally) fronts together with the wh-word. Either way, the embedded verb must still agree with its own subject in tense and number.

1. Identify the frame: "Do you know ________?" already supplies the question force through "Do you know", so the clause after it must read like a statement, not a fresh question — no repeated auxiliary and no inversion.

2. Check subject-verb agreement: the subject inside the blank is the third-person singular "she", so the present-tense verb takes the "-s" ending: "comes", not "come".

3. Assemble in embedded order: wh-word + subject + verb + preposition gives "where she comes from" (the common, stranded-preposition pattern).

Cross-checking against the rejected options confirms this: the option that re-inverts the auxiliary ("does she come") reintroduces direct-question structure that an embedded clause must not use; the option that fuses "where" and "from" into one fronted unit ("where from she comes") matches neither the stranded nor the separately-fronted preposition pattern; and the option that fronts the preposition correctly as "from where" nonetheless fails because its verb "come" does not carry the "-s" agreement needed for "she" — an agreement lapse, not a word-order one.

Hence, of the four, only "where she comes from" is both correctly ordered and correctly agrees with its subject; the correct completion is "where she comes from."
