Do you remember how long ago （）to China A. have you traveled B. you have traveled C. did you travel D. you traveled

This question tests the grammar of embedded questions and tense usage. When a question is embedded as an object clause after verbs like "remember," we use statement word order (subject before verb) instead of question order. Additionally, "how long ago" specifically refers to a completed past time, requiring the simple past tense rather than present perfect.

Analysis of options:

A ("have you traveled") and B ("you have traveled") use present perfect tense, which is incorrect here because "how long ago" indicates a specific past time, not a connection to the present.

C ("did you travel") uses question word order (auxiliary "did" before subject "you"), which is inappropriate for an embedded clause.

D ("you traveled") uses simple past tense and statement word order, matching the requirements of "how long ago" and the embedded question structure.

Answer: D
