No, a comma does not always go after "therefore." It depends on the sentence structure and how "therefore" is being used within the context of the sentence.
Not necessarily either. There is no word or phrase in English that requires a comma. Commas are a feature of sentence structure, not of words. " Your data is incomplete and your conclusion is therefore wrong." both before and after UNLESS its at the start of a new sentence "i like to run, therefore, i run a lot. yes, but should also reference to lexis and structures.
yesAnother view"I don't think the first answer is correct. For example, in the sentence:Though it was very cold outside, she did not wear a coat.If the sentence were to be reworded though, then a comma would go after it.
The comma goes before "therefore" when it is used to connect two independent clauses. The semicolon goes before "therefore" when it is used to separate two closely related independent clauses.

After Example: Therefore, the restaurant was terrible.
No, the comma does not always go after "nowadays" at the beginning of a sentence. Whether a comma is needed depends on the context and the rest of the sentence. If "nowadays" is being used to introduce a contrast or emphasize a point, a comma may be used. However, if "nowadays" is used as part of the subject or the main idea of the sentence, a comma may not be necessary.
YES
Before
There is no word in English that necessarily requires a comma. Commas are features of the sentence. Sometimes a comma may go before if, for example when it introduces a new clause: We will wear rain-gear, if it becomes necessary. And sometimes a comma may go after if, for example in this sentence, when another thought is inserted into the structure. Generally there is no comma with if.
The comma in the word "but" is typically not included unless it is used at the beginning of a sentence to introduce a contrasting idea. For example, in the sentence "I wanted to go to the movies, but I had to study," the comma follows "movies" before "but."
The comma should be placed after "Greece". The corrected sentence is: "Should you go to Greece, or should you go to Kenya?"
