Reading Comprehension:
Layla's Visit to the Post Office Read the following passage and then complete the task below: It is Monday morning and Layla is all ready to go into town. She has to go to the post office to send off a few things, pay two bills and send some money. She bought a beautiful gift for her mother's birthday and decided to send it to her in the post. It was too risky to travel down to Plymouth with the Omicron spreading so quickly. The post office wasn't very crowded and she was served immediatly. As her parcel had an expensive vase inside, the postmaster advised her to send it to be signed for. While she was there, she sent a letter to her lawyer first class and another to her GP second class. When the postmaster finished with her post, she paid her council tax and water bill. On her way to the post office, she noticed she was out of credit and needed a twenty five pound mobile top up. It was also time for her to top up her gas & electric meter. The last thing on her list was to transfer money to her sister living in Jorden. As the post office has the Money Gram service, she was able to send money after providing the correct ID. After she finished what she needed to do, the queue was very long with lots of unhappy custumers waiting patiently for their turn to be served.

1.Where is Layla going?.
