[Q]: Question: Possible Duplicate: "Did it close" vs "Has it closed"? As a English non-native speaker it is difficult for me to understand when I must use present perfect or past simple because in my official language there isn't the present perfect tense. I know that present perfect is related to something that happened in the past but its result is important now. But for instance: The message has been sent. The message was sent. Please help me point me out any examples/contexts where I should use 1. instead of 2. 
Answer: 1 means that the action happened just now. You would typically see it in your e-mail program just after you send an e-mail. Your program might give you this message to let you know that the message you just sent has indeed been sent. 2 refers to something that happened at some time in the past. It could have been an hour ago, a day ago, or even a century ago! But it wasn't just now.
[A]: yes


[Q]: Question: I am looking for a single adjective to describe someone who is easily discouraged. Example: Any person who is (easily discouraged) will not get far in life 
Answer: Someone who is not perseverant or persistent is relenting. Often we see the "un-" negation of this word, as in unrelenting rain. Someone who gives up easily yields or concedes, and that makes him or her yielding and concessive. Someone who lacks resolve or determination is irresolute, indecisive, undetermined.
[A]: no


[Q]: Question: Most grammar checkers are capable of detecting the the misuse of "your" and "you're"; providing the necessary correction. I'm curious though, is there any sentence that can be constructed where replacing "your" with "you're" keeps the sentence grammatically correct, but changes the meaning? If this is not possible, what grammar rules are in place that prevents these edge cases from occurring? 
Answer: a. I love you and your bananas. b. I love you and you're bananas. This particular case depends on the your/you're coming after an independent clause followed by "and," since its feasibility depends on functioning either as a second direct object or as another independent clause. It also depends on the noun serving either as a thing that someone might be in possession of (the bananas we eat) or as an adjective or noun complement describing a person (bananas=crazy). Easiest if that noun is plural or uncountable. The same sentence could be constructed with nuts, garbage, and other nouns which I'll let you brainstorm because my stormer hurts. You can also (and thanks to @Barmar for drawing attention to this) use verbs, in which case they act as a gerund with the possessive pronoun and a present participle with the "you're." As in: a. I love you and your cooking. b. I love you and you're cooking. Or: a. I despise you and your smoking. b. I despise you and you're smoking.
[A]:
yes
