2022 P=HT 6. 次のお知らせを読み、 (1) ~ (2) のA~Dで適切なものに○をつけなさい。 [4×2=8] TO: All staff From: Erin Liner, Manager Date: July 15 Subject: Our survey Dear all. We have finished reviewing the data which we received from the recent customer satisfaction survey. I would like to share the most important findings, and how we can improve on certain areas of our work. Overall, customers were happy with the quality of our service. the helpfulness of our staff, and the range of products we offer. However, there were some negative comments which we can begin to work on. A common complaint was that there are not enough foreign titles in the store, especially Japanese comics. I will ask John Calman to research some of the most popular series and make sure we start carrying them from the fall. As Gita Pradesh spent her college years in Tokyo, I will ask her to assist. Better signage was another thing which people wanted. They spend a lot of time looking for the right section and it frustrates a lot of customers. This is something we can improve immediately, so I will speak to Alice Moore today about making the signs easier to see, and adding more if necessary. Finally, we got some comments about having a small cafe in the store. Nowadays, people want to have a coffee while reading or browsing, and it could be a new source of profit. Mario Venetti will make a report on the feasibility and deliver it next month. Thank you for all your efforts in making us the best we can be. Erin Liner Manager (1) What is the purpose of the e-mail? (A) To ask staff to create survey questions (B) To share details of customer feedback (C) To inform staff of recent changes (D) To invite staff to apply for new positions (2) Where does Ms. Liner most likely work? (A) At a café (B) At a movie theater (C) At a clothing shop (D) At a bookstore 以
