l am not walking to school with her
Bob has seen something strange
l am doing an easy exercise

Answer 1

* Bill and Tom didn´t answer the questions, did they?
* I am not walking to school with her, am I?
* Bob has seen something strange, hasn´t he?
* I am doing an easy exercise, am I not? - Esta é a tag question correta. No entanto, informalmente, muita gente (sobretudo os americanos) utiliza a expressão ´´aren´t I?´´ , que não deve considerar na escrita, pois não é ´´correct use of English´´.
* Tom and Ted have finished the exercises.
