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.

“Since the sample is too small for a bacterium that is used in the investigation, then it is not valid” best explains why the researchers’ conclusion was not justified.

at nineteen years old, nicole c. kear's biggest concern is choosing a major--until she walks into a doctor's office in midtown manhattan and gets a life-changing diagnosis. she is going blind, courtesy of an eye disease called retinitis pigmentosa, and has only a decade or so before lights out. instead of making preparations as the doctor suggests, kear decides to carpe diem and make the most of the vision she has left. she joins circus school, tears through boyfriends, travels the world, and through all these hi-jinks, she keeps her vision loss a secret.

when kear becomes a mother, just a few years shy of her vision's expiration date, she amends her carpe diem strategy, giving up recklessness in order to relish every moment with her kids. her secret, though, is harder to surrender - and as her vision deteriorates, harder to keep hidden. as her world grows blurred, one thing becomes clear: no matter how hard she fights, she won't win the battle against blindness. but if she comes clean with her secret, and comes to terms with the loss, she can still win her happy ending
