following early draft of an essay and then choose the best answer to the question or the best completion of the statement. Passage (1) Many people mistakenly assume that buttermilk is a high-fat, buttery form of milk-something akin to heavy cream (2) However, this is far from the truth. (3)Today's buttermilk is lower in fat than most regular milk is, and surprisingly, does not contain any butter at all. (4) Before the 1920s buttermilk was indeed composed of the milky byproduct of churned butter. (5) This kind of buttermilk often called "real buttermilk " had a rich and creamy taste. (6) Real buttermilk was generally produced in a family's butter churn and was used in recipes for baked goods such as pancakes or biscuits. (7) These were popular breakfast foods at the time, and remain so today. (8)However, once butter production shifted to factories, real buttermilk ceased to be used in most home cooking, for the simple reason that most families were no longer churning their own butter. (9) Present-day buttermilk is produced not from butter but from skim or low-fat milk. (10)After the milk is pasteurized and cooled, certain cultures are added to give it buttermilk's acidity and flavor.(11) The buttermilk is then left to "ripen," a process that takes approximately fourteen hours. (12) Once the process is complete, the buttermilk is stirred and cooled (13) This kind of buttermilk is generally referred to as "cultured buttermilk" because of the bacteria added to it. (14) Its taste is generally much more acidic and sour than that of real buttermilk. Question In context, which sentence would be best to insert at the beginning of paragraph 3 (sentences 9-14)? Today, buttermilk is made in a different way than it was made in the past. Modern buttermilk tastes better than the buttermilk that was made before 1920. Many people today are not familiar with the various uses of buttermilk. Buttermilk has lost its popularity largely because of the difficult process of making it.
