Why the results of the Swan-neck flask experiment were reliable ?: Select one: a. Because it maintained no controls at all b. Because proper controls were maintained and only one variable changed at a time c. Because many controls were maintained d. Because it was repeatedly done by several scientists e. Because it tested all variables at the same time
