Hi Alex,

                   Thank you for doing your homework once again. Just got few corrections. It's just about spelling and the proper usage of these. These is the plural form of this. So if your referring to two or more object you have to use 'these'. Don't forget to use the proper punctuation like period(.); comma(,) or exclamation(!). See you in our next class Alex. Have a goodnight sleep!^*^
