You can also use the word "via". "... and send them to the group via telegram..." Via means "by way of" and you could also substitute those words for via.

I agree with Mena. I'm trying to think how I can help explain why #1 is incorrect. I'm a native speaker but not an English teacher. The part of the sentence that sounds incorrect is "is to you". "Is for you" can be used. Examples: The best option is FOR you to either do A or B. The best option is FOR you to do either A or B. Those don't sound incorrect, they sound OK but it feels more natural to put "is" after "you".

Here are a couple examples of using these words in different ways: "That was a knee slapper" is a phrase which refers to the reaction a person has to a joke, they slap their knee with their hand. "She smacked her lips" is a phrase meaning a noisy way to close and open your lips. Slapping is typically an action performed with the hand or something that reminds you of that action. I could use both in a sentence like "the board slapped to the ground with the sound of a smack". Suppose my face was red in color and I was asked "What happened". If I respond with "I was slapped in the face" versus "I was smacked in the face" the difference is, in the case of "slapped" I would assume by someone's hand, but with "smacked" it could have been by hand but also a tree branch or something else that hit me in the face. In the first case I might ask "Who hit you" where in the second case I might ask "What hit you". In the case of hitting a person, as you said, slap is specifically an open hand. My mother-in-law has a funny phrase which sounds like it was used over 50 years ago (not something you'd hear today), it goes "I'll smack you so hard it'll jar your kinfolk". Which means the hit will be so hard that your relatives will feel it. "Wallop" is another fun one that means a hard hit though this is also an older word and I can't recall the last time I heard someone say it.

@Stu, I'm going to guess for #3 that "The tie against one of the leaders" could possibly mean "the connection with one of the leaders" and "came to handy to us" would likely be "came in handy for us" Best guess at the meaning: 3) "Our ties with one of the leaders came in handy because we were struggling in the regulation zone" What is particularly difficult between English and Russian is English uses "the" and "a" (definite and indefinite articles). The two languages have different ways to specify what the topic is in a sentence. In English this sentence might use "A tie with one of the leaders" or "The tie with one of the leaders" and end with "in the regulation zone" or "in a regulation zone". If previous to this sentence the reader knows which regulation zone in particular, then "the regulation zone" can be used. So to properly translate this sentence in English we need to know more about what the reader knows about "tie" and "regulation zone" to know if we should use (a/the).

This sounds like a matching exercise. Are there pictures for you to match the numbers to?

As a native English speaker I find this text VERY difficult to read without analyzing it very carefully. I would say you are correct in all 3. When you mine something you retrieve something of value. I don't know what "the death drive" is or "unpleasurable pleasure" is. "unpleasurable pleasure" is an oxymoron. Oxymorons are purposely confusing. It makes me think the author of this text wants the reader to know that the author is a profound person.
