I'd love to visit a museum - can you help me find one, please?
Sure.  There are 23 museums in Cambridge.  Is there a particular area or type of museum you are interested in?
I do not have a preference on the area.
How about the byard art museum located at 14 king's parade? 
That sounds intriguing.  What area is that in?  And is there an entrance fee?
It is in the south and admission is free
Are there any in the centre you can tell me about as well?
Yes. There are 11 in the centre. Would you like to know more about one?
Can you suggestion one?
The broughton house gallery is very nice
How much does it cost to get in? My funds are very limited
no entrance fee charged
Grand. Can I also get your help with  train? I need to get to Stansted airport by 16:45 on Wednesday.
And where are you leaving from?

Train TR0678 will arrive by 16:08. Is that ok for you? 
No.  The train needs to leave after 16:45.
I have gotten two different responses. You said you need to arrive by 16:45 and leave by 16:45. It can only be one or the other.
I need to leave after 16:45 please.
Ok great, the TR8893 will fit your needs. How many tickets do you need?
No tickets, just the arrival time and I am all set.
The arrival time is 18:08.
