If youve ever had the thought "Should I use Whos or Whose" then you need this app Exploring Language: Whos vs. Whose. Sometimes it is difficult do differentiate meaning between two different words which sound identical. This is certainly the case with Whos vs. Whose. Ive known many friends who have struggled with this throughout the years and so this app is for them. Included is a brief explanation of the difference between Whos and Whose, 50 sample sentences of each, mixed up flash cards to test your understanding, as well as a randomized multiple choice section, to really drill it home. I hope this application solves this issue for you, your friends, your family, or your students.
