Hey Nahdiah, In your example, the correct answer is ''i.e.'' ''Namely'' and ''i.e.'' are both used to give more information about something that you have just mentioned. 1) 'namely' = you use 'namely' to say exactly what you mean when you have just referred to something in a general or indirect way. It means ''specifically.'' E.g.: ''One group of people seems to be forgotten, namely pensioners.'' E.g.: ''We shall answer/atone for our misdeeds, namely our sins.'' 2) 'i.e.' = you use 'i.e.' when you are giving an explanation of a word or expression that you have just used. It has the meaning of ''in other words'', ''that is (to say).'' E.g.: ''You must be an amateur, i.e. someone who has never competed for prize money in athletics. E.g.: ''Are you familiar with the popular social media? i.e., Facebook, Instagram, Skype, Whatsapp and so forth.'' Hope that helps!!!

Here it is i.e. i.e. introduces an alternative explanation for something you have just described - it means "that is" or "in other words". Namely means 'specifically' - in this context, for example: namely January and February.
