Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified?

Read the excerpt from "mother tongue." lately, i’ve been giving more thought to the kind of english my mother speaks. like others, i have described it to people as “broken” or “fractured” english. but i wince when i say that. it has always bothered me that i can think of no other way to describe it other than “broken,” as if it were damaged and needed to be fixed, as if it lacked a certain wholeness and soundness. what best supports the inference that tan believes nonstandard english is no less valid than standard english? tan spends a lot of time thinking about her mother’s “fractured” english. tan has trouble thinking of descriptive words when she is writing. tan’s american education makes it difficult for her to understand her mother. tan winces when she describes her mother’s english as “broken.”
