Explanation:

1)

• For the first blank, "is open" is used to describe the state of the museum being open, while "opens" is an action verb (like the museum opens the door, but here we mean the state of being open during a time period). So "is open" is correct.
• For the second blank, "from...to..." is a fixed prepositional phrase to indicate a time range, so "to" is correct.

• The word "yesterday" indicates past tense. "said" is the past tense of "say", while "says" is present tense. So "said" is correct for the first blank.
• For the second blank, since the action happened yesterday, we use the past tense of "go", which is "went", and "go" is present tense, so "went" is correct.

• "travel" is the base form of the verb. Here, the sentence is in simple present tense to state a general fact about the tourists' way of traveling. "traveling" is a gerund or present - participle, which can't be used as the main verb in this simple - present - tense sentence. So "travel" is correct for the first blank.
• "by +交通工具" is a fixed structure to indicate the means of transportation, so "by" is correct for the second blank.

Answer:

This museum (is open) from 9:00 a.m. (to) 6:00 p.m.
