Though and although can be used interchangeably. Although is considered to be more formal than though. See is inactive, your eyes are open and it happens without thinking. (I see the screen). Look is more active, it is brief but you intend to do it. (Look at me when I am talking to you) The word other goes before a plural noun (other people, other foods, etc) another goes before singular nouns (another person, another food, etc)
