Stimulus

Most regular coffee is made from arabica coffee beans because the great majority of consumers prefer its generally richer flavor to that of coffee made from robusta beans. Coffee drinkers who switch to decaffeinated coffee, however, overwhelmingly prefer coffee made from robusta beans, which are unlike arabica beans in that their flavor are flavor-neutral but one of which contributes to the richness of the coffee’s flavor.

Answer choices

  1. Out of Scope: annual world crop0% picked this

    The annual world crop of arabica beans is not large enough to satisfy completely the world

    This answer is full of out of scope ideas. We don't have any information about the size of the annual world crop of arabica beans, the demand for regular coffee, or the relationship between the two.

  2. Out of Scope: caffeine1% picked this

    Arabica beans contain more caffeine per unit of weight than do

    As sacrilegious as this sounds, this question about coffee has nothing to do with caffeine. We already know why folks generally prefer arabica: its richer flavor. We can't infer anything about caffeine content from that.

  3. Unsupported Comparison7% picked this

    Coffee drinkers who drink decaffeinated coffee almost exclusively are the ones who prefer regular coffee made from robusta beans to regular

    We know there are regular robusta drinkers, and we know there are decaf robusta drinkers, but we don't know whether there is any overlap between these groups.

  4. Correct90% picked this

    Decaffeination of arabica beans extracts more of the substance that enhances a coffee's flavor than does

    Why this is right

    Decaffeination only impacts one substance that contributes to flavor. And the flavor of Arabica beans is impacted more than the flavor of robusta beans. From this, it's pretty reasonable to conclude that the one flavor substance is getting hit harder in the arabica beans than the robusta beans. And if you had any doubts about picking an answer that implies that the decaffeination process could differ from bean to bean, look no further than the last sentence to resolve that qualm: "Depending on the type of bean involved..."

  5. Out of Scope: cost1% picked this

    There are coffee drinkers who switch from drinking regular coffee made from arabica beans to drinking decaffeinated coffee made from arabica beans because coffee

    The stimulus says nothing about cost, nor does it allow us to infer a relationship between regular arabica drinkers and decaf arabica drinkers.
