Well, businesses are finding that ethnography can offer them deeper insight into the possible needs of customers, either present or future, as well as providing valuable information about their attitudes towards existing products.
題目解析：利用customer needs進行定位，as well as 和題干中的and為同義表達。
They saw that the cooks had to check and recheck the contents, because although the measuring cups had numbers inside them, the cooks couldn't see these easily.
題目解析：cooks 和 measuring up可以定位聽力原文，容易得到答案numbers，因為限定詞為cups是復數形式，所以答案也是復數形式。
Because these customers paid in advance for their calls, they were eager to know how much time they'd spent on the call so far.
題目解析：because 引出的原因句為考點，wanted to check和eager to know為同義表達。
It was found that a large amount of their work involved communicating with colleagues in order to solve problems, but that they didn't have a standard way of exchanging information from spreadsheets and so on. So the team came up with an idea for software that would help them to do this.

Occasionally, research can be done even in environments where the researchers can't be present. For example, in one project done for an airline, respondents used their smartphones to record information during airline trips, in a study aiming at tracking the emotions of passengers during a flight.

So what makes this type of research special is that it's not just a matter of sending a questionnaire to the participants, instead the research is usually based on first-hand observation of what they are doing at the time.
題目解析：轉折詞都是考點，在此題中，instead 表達強調和轉折，based on first-hand observation 同義表達于有direct observation。
