1.   Clark based his opinions on reviews of the autopsy reports and other information from the case.

2.   Smith told me that his opinion was based upon his subjective interpretation of the statutes.

3.   That opinion was based on an interview Viza had with a foreign ministry official.

4.   Her opinion is based on a careful scrutiny of the text.

5.   Otherwise my opinion may be based on ignorance.

6.   Art dealers and other experts had based their opinions on photographs in the auction catalog.

7.   Baratz based his opinion that Falater was not sleepwalking on the eyewitness account of a neighbor who looked over a wall after the stabbing.

8.   But if popular opinion is not based on informed deliberation, the use of it by elites does not truly enhance democracy.

9.   But the owner was not basing his opinion on what he watched the fizzling Yankees do against the Orioles last weekend.
