I want to know the answer to the following question:
What is Tucson's CBS station?
All the background I'm provided with is that "The major television networks serving Tucson are: KVOA 4 (NBC), KGUN 9 (ABC), KMSB-TV 11 (Fox), KOLD-TV 13 (CBS), KTTU 18 (My Network TV) and KWBA 58 (The CW).". Is that enough to answer the question?
Answer: yes
