Focus on the explanations below.1Her hair was wet when she opened the door — she in the pool. (swim)Correct answer: had been swimming▸ Why?A past visible state (wet hair) explained by an earlier activity → PPC. Past simple "swam" would close the swim off as a finished episode; PPC keeps the cause-and-effect alive at the moment of opening the door.2His face was red and damp when he sat down — he in the gym for nearly two hours. (train)Correct answer: had been training▸ Why?A past visible state (red, damp face) + a duration ("for nearly two hours") → PPC. Past perfect simple "had trained" would close the training off and weaken the visible-aftermath explanation.3There was sawdust all over the workshop floor — Andreas a new bookshelf since dawn. (build)Correct answer: had been building▸ Why?A visible past consequence (sawdust) traced back to a starting point ("since dawn") → PPC. Past simple would lose the dawn-to-now stretch; past perfect simple would suggest the bookshelf was already finished.4The kitchen smelled wonderful when I came home — Mum all afternoon. (bake)Correct answer: had been baking▸ Why?A past sensation (smell) caused by an extended earlier activity → PPC. "Had baked" suggests the activity was over and tidied away; the lingering smell argues for an activity that had only just stopped.5The children's clothes were filthy by teatime — they in the garden since lunchtime. (play)Correct answer: had been playing▸ Why?A visible past state (filthy clothes) traced back to "since lunchtime" → PPC. Past simple would lose the lunchtime-to-teatime stretch that explains how the clothes got that dirty.6Marie's eyes were red and puffy at the funeral — she since the news first broke. (cry)Correct answer: had been crying▸ Why?A past visible state explained by a sustained earlier activity ("since the news") → PPC. Past simple "cried" would describe a single event and lose the on-and-off stretch that produced the puffy eyes.7When he tried to speak after the match, his voice was completely hoarse — he at the rugby for two hours. (shout)Correct answer: had been shouting▸ Why?An audible past consequence (hoarseness) + "for two hours" → PPC. Past simple would lose the prolonged cause; past perfect simple would lose the still-recent feel that explains why his voice was gone right after.8The detective noticed that the suspect's hands were trembling — he a heavy bag for some time. (carry)Correct answer: had been carrying▸ Why?Past visible evidence (trembling hands) explained by a sustained earlier activity → PPC. Past simple would lose the duration that explains the tremor; past continuous would only describe a single moment.9When we found Tom asleep at his desk, the empty coffee cups around him suggested he on the report all night. (work)Correct answer: had been working▸ Why?Past visible evidence inviting an inference about the night before → PPC. Past simple "worked" would close the activity; PPC captures the long, sustained effort the cups bear witness to.10The dog's fur was matted with leaves and twigs when he limped back home — he in the woods for hours. (run)Correct answer: had been running▸ Why?A past visible state explained by a long activity ("for hours") → PPC. Past simple would lose the duration; past continuous would mark only a moment, not the hours that produced the mess.11There was a strong smell of bleach in the kitchen when I arrived — someone the floor obsessively for ages. (clean)Correct answer: had been cleaning▸ Why?A past sensory clue (sharp bleach) caused by sustained earlier activity → PPC. Past perfect simple "had cleaned" would suggest the cleaning was already finished and aired out, which the still-strong smell contradicts.12I could see from the muddy boots in the hall that my brother along the river path again. (walk)Correct answer: had been walking▸ Why?A past visible clue inviting an inference about an earlier activity → PPC. Past simple "walked" would describe a closed past trip; PPC captures the recurring (note "again") activity the boots bear witness to.13Anna's fingertips were stained dark blue by lunchtime — she ink samples in the lab all morning. (test)Correct answer: had been testing▸ Why?A past visible state (stained fingertips) + "all morning" → PPC. Past simple would close the morning off; PPC keeps the sustained testing alive as the explanation for the stains.14The whiteboard was covered in arrows and crossings-out — the team for hours and clearly hadn't reached agreement. (brainstorm)Correct answer: had been brainstorming▸ Why?A past scene (chaotic whiteboard) + "for hours" → PPC. Past continuous would mark a moment and lose the hours of work; past perfect simple would suggest the discussion was already over and tidied up.15His jacket smelled strongly of woodsmoke when he walked in — he leaves in the garden for most of the afternoon. (burn)Correct answer: had been burning▸ Why?A past sensory clue (smoky jacket) + a long duration → PPC. Past simple would close the action; past perfect simple would suggest the fire was already long over, which the strong lingering smell contradicts.Check AnswersPlease answer at least one question first.Found an error in this exercise?
