D. No improvement<\/strong><\/p>\nThe sentence “Who does not know that this was broadcasted ten days ago?” is grammatically correct and uses the past tense correctly. The past tense is used to describe events that happened in the past, and the sentence is describing an event that happened ten days ago.<\/p>\n
Option A, “had broadcast,” is also grammatically correct, but it is not the best choice for this sentence. The past perfect tense is used to describe events that happened before another event in the past, and the sentence does not need to use the past perfect tense.<\/p>\n
Option B, “was broadcast,” is also grammatically correct, but it is not the best choice for this sentence. The simple past tense is used to describe events that happened at a specific time in the past, and the sentence does not need to use the simple past tense.<\/p>\n
Option C, “was broadcasting,” is not grammatically correct. The present progressive tense is used to describe events that are happening now, and the sentence is describing an event that happened ten days ago.<\/p>\n
Therefore, the correct answer is: D. No improvement<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"[amp_mcq option1=”had broadcast” option2=”was broadcast” option3=”was broadcasting” option4=”No improvement” correct=”option4″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[659],"tags":[],"class_list":["post-10128","post","type-post","status-publish","format-standard","hentry","category-sentence-improvement","no-featured-image-padding"],"yoast_head":"\n
