Dear teacher,
Those who have created the businesses say that using the Web cuts costs and increases efficiency. They can find fellow students to act as Web developers for far less than the cost of hiring a professional. With orders coming in through the Web site, they avoid having to staff telephone lines, and there is no storefront to maintain.
Q : Does "having to" mean "must"?
Q2: "staff telephone lines" means "connect telephone lines" or "have a telephone", doesn't it?
Having to
