Let's analyze each question and identify the errors. The questions test your understanding of English grammar, specifically tense usage and sentence structure.<br /><br />**Question 9 [83148]:** Correct. "No sooner...than" is a correct correlative conjunction structure.<br /><br />**Question 10 [83149]:** **Error in C.** The sentence should read "...to thirty percent *by* the end of 2019..." The use of "by" indicates the point in time when the increase was reached.<br /><br />**Question 11 [83150]:** **Error in B.** The sentence describes a past action at a specific time in the past. It should use the past continuous: "At this time last year, I *was* attending..."<br /><br />**Question 12 [83151]:** **Error in C.** The sentence should use the past perfect: "...somebody *had* broken into the flat." This indicates the breaking-in happened *before* they got home.<br /><br />**Question 13 [83161]:** **Error in D.** The sentence uses two past continuous verbs, but the actions are not simultaneous. It should be: "...I *watched* the smartphone." or "...I was watching the smartphone." depending on the intended nuance.<br /><br />**Question 14 [83162]:** Correct. The past perfect continuous ("had been watching") correctly shows an action in progress before another past action.<br /><br />**Question 15 [83163]:** **Error in B.** The conditional clause uses the present simple ("continues"), so the main clause should use the future simple ("will drink") to maintain consistency.<br /><br />**Question 16 [83164]:** Correct. The sentence correctly uses past simple to describe a sequence of events.<br /><br />**Question 17 [83165]:** Correct. The sentence correctly uses past simple to describe two actions in the past.<br /><br />**Question 18 [83166]:** **Error in A.** The sentence should use past simple: "...we *stayed* up..." The past perfect ("had stayed") is unnecessary and creates redundancy with "had lived".<br /><br />**Question 19 [83167]:** **Error in B.** The sentence should use the superlative correctly: "...the worst dish *I have ever tried*..." The present perfect is needed to encompass the speaker's entire life experience.<br /><br />**Question 20 [83168]:** Correct. The sentence correctly uses past simple and past perfect to show a sequence of events.<br /><br /><br />In summary, the errors primarily involve incorrect tense usage, specifically the misuse of past simple, past continuous, and past perfect tenses. Understanding the nuances of these tenses and their appropriate application is crucial for accurate sentence construction in English.<br />
