阅读以下说明,回答问题1和问题2。
【说明】
传统的电视采用单向广播方式,极大地限制了电视观众与电视服务提供商之间的互动,也限制了节目的个性化和即时化。如果一位电视观众对正在播送的所有频道的内容都没有兴趣,他将别无选择。这不仅对该电视观众来说是时间上的损失,对有线电视服务提供商来说也是资源的浪费。另外,目前实行的特定内容的节目在特定的时间段内播放对于许多观众来说是不方便的。一位上夜班的观众可能希望在凌晨某个时候收看新闻,而一位准备搭乘某次列车的乘客则希望离家以前看一场原定晚上播出的足球比赛录像,这在传统的电视广播方式中是不可能的。

Background information

B-Star is a theme park based on a popular series of children*s books. Customers pay a fixed fee to enter the park, where they can participate in a variety of activities such as riding roller-coasters, playing on slides and purchasing themed souvenirs from gift shops.

The park is open all year and has been in operation for the last seven years. It is located in a country which has very little rainfall- the park is open-air so poor weather such as rain results in a significant fall in the number of customers for that day (normally by 50%)。 During the last seven years there have been on average 30 days each year with rain.

B-Star is now very successful; customer numbers are increasing at approximately 15% each year.

Ticket sales

Customers purchase tickets to enter the theme park from ticket offices located outside the park. Tickets are only valid on the day of purchase. Adults and children are charged the same price for admission to the park. Tickets are preprinted and stored in each ticket office.

Tickets are purchased using either cash or credit cards.

Each ticket has a number comprising of two elements 每 two digits relating to the ticket office followed by six digits to identify the ticket. The last six digits are in ascending sequential order.

Cash sales

1. All ticket sales are recorded on a computer showing the amount of each sale and the number of tickets issued. This information is transferred electronically to the accounts office.

2. Cash is collected regularly from each ticket office by two security guards. The cash is then counted by two accounts clerks and banked on a daily basis.

3. The total cash from each ticket office is agreed to the sales information that has been transferred from each office.

4. Total cash received is then recorded in the cash book, and then the general ledger.

Credit card sales

1. Payments by credit cards are authorised online as the customers purchase their tickets.

2. Computers in each ticket office record the sales information which is transferred electronically to the accounts office.

3. Credit card sales are recorded for each credit card company in a receivables ledger.

4. When payment is received from the credit card companies, the accounts clerks agree the total sales values to the amounts received from the credit card companies, less the commission payable to those companies. The receivables ledger is updated with the payments received.
