CHOOSE THE CORRECT ANSWER 1) She ______ breakfast 2) They have ______ home 3) He ______ the vase 4) I have ______ him since infancy 5) Have you ______ your book?

The exercise tests the correct use of present perfect tense (have/has + past participle), especially with time expressions like "since."

Option 1: She ___ breakfast whatever
Formula: Present perfect would be "has eaten," but "breakfast whatever" is incomplete/awkward (likely meant for present simple habit: "eats"). Incorrect.

Option 2: They have ___ vase home
Formula: Possession uses present simple "have a/the vase at home." "Home" needs "at." Incorrect for present perfect.

Option 3: He has broken the vase
Formula: has + broken (past participle). Correct for present perfect (action completed, result now relevant). Possible, but no specific time marker requiring it.

Option 4: I have known him since infancy
Formula: have + known (past participle). Correct for present perfect. "Since" requires present perfect for duration from past to present ("I knew... since" would be wrong).

Option 5: Have you ___ your lost find
Formula: Question form present perfect: "found." But "lost find" is unclear phrasing (perhaps "lost-and-found"?). Awkward.

Option 4 perfectly matches present perfect with "since" for ongoing state.

4) I have known him since infancy
