Answer and Explanation:
Helen's hands shook when she answered the phone. Even though she had been waiting for that call all week, she was not ready. What-if’s filled her mind uselessly. What if they said she had failed? What if they had found a better candidate for the position? What if she had not failed? What if she got the job and had to move away from everything she knew? She answered, trying to somehow disguise her trembling voice. The woman on the other side of the line sounded cheerful. It was good news; Helen got the job. She thanked the woman, once, twice. Yes, she could start in two weeks. Once she hung up, reality came rushing back. Time to tell her friends and family.
