which one of these usages is correct? "at one point of time" (or) "at one point in time" ?
101981
Using "of" indicates a specific point or instance during the event.  Using "in" indicates that the event is continuous or over a certain period.  In this case, the event is ambiguous as to its length, and so "at one point in time" is correct, whereas "at the start of the evening" indicates specifically when.

C. Would you care if I went too?\n\nYou can tell that this is the answer if you read it substituting the word 'too' with 'also'.\n\nWould you care if I went also? \n\nIt makes sense to use either word so "C" is correct.\n\nYou can substitute the word "also" in the other answers as well. However, when you do this, it changes the meaning of the sentence.\n\nHope you find this helpful.

What time will your plane arrive? (Asks future tense, not present perfect - basically its the only one that sounds normal.)\nBy the time he comes home, I will have finished dinner. (Tense is correct.  Specifies event passed not event occuring)\nHe can predict how many people will be living in these regions.  (Can predict specifies indefinite future)\nThey will soon be able to solve the problems. (The other one simply does not make sense.)\nAccording to the timetable, the plane arrives at 7PM (For all I've been taught you want to avoid wordiness and to be verbs.  I'm honestly not really sure on this one.)

"When" is not a question- rather an assertation of the eventuality of all things.  As all things are in constant change; eventually, all things become all things.  There is no "if", only "when".\n\nFurther, "now", is the essence of this very moment.  Just as an object can either be precisely measured in space or velocity- but not both- so is the everchanging world around us measurable only in the moment.  "Now" is synonymous, therefore, with "what".\n\nSince all things in their eventuality are the same, and yet immeasurable when removed from their essence, and all things measured are themselves momentary, so too are all things when, all things if, all things now, and all things what.  The world defies our attempts to measure it, and escapes our understanding as soon as we require it.

depends on how you use it....\n\nI was lying down.\nHe is laying down.\n\nOne is past tense the other is present tense.

In response to your first question, the use of the word "their" in this case is quickly becoming colloquially acceptable in replacement of "his or her" or "your."  This has always been an awkward point in the English language.\n\nIn the second case, the use of "since" implies that the action is still taking place, but the use of "were" implies that the action has been completed.  Therefore, if these cultures still exist and are agricultural, "have been" is correct.  If these cultures no longer exist, then "since" must be eliminated in favor of something more clear.

Question of when, not if.

The first one is correct because "lately" implies a link between present and past, and that's the "present perfect" (have slept).\nThe second one is completely incorrect because the tense "present" doesn't draw this link between present and past.

I think it would be better like this: ....... if you dont listen to me WHILE I talk to him on the phone.\nYou are supposed to use "While" when the action goes on for a length of time".\nAnyways, I dont think you should really worry since the average native speaker doesnt use grammatically correct sentences.

I can't believe all these people saying "Mark and I"  !!!  "Mark and me" is correct!\n\nSimply take "Mark" out of the sentence and see if it sounds right.\n\n"Could you please copy I on these communications?"  It doesn't work!\n\nAnd the first one is correct.  The second sentence uses the reflexive pronoun "myself," which doesn't make any sense.  Could you please copy myself on these communications?  You would not ask somebody to do it, if you were going to do it yourself.
