i just wanted to inform you about a change to Mr. Clackson's schedule when she visits the branch here in San Diego next week. She will be visiting the head of research, Dr. Leo, at the laboratory facilities at 9:30 A.M. on Monday. Unfortunately, branch director Kyle Mason will not be back from his business trip at that time, so we'll be change that appointment to Wednesday at 10 A.M. Please reply if you have any questions.

Q. What is indicated about Ms. Clarkson?

(a) She will be speaking to Dr.Leo about a job on Wednesday morning. 

(b) She was previously scheduled to meet with Kyle Mason on Monday.

※ speak to:이야기를 걸다

답은 (b)인데요. 왜 (a)가 틀린 선택지인지 잘 모르겠습니다. 실험실 방문해서 말을 한 마디도 안하지는 않을건데.. 충분히 추론가능하지 않나요? 읽어주셔서 감사합니다ㅎㅎ
