Answer:

C. The scientist's conclusion is flawed because the number of hours of sunlight changed and, therefore, the experiment is not controlled.

Explanation:

A controlled experiment is an experiment used to test a single variable at a time. The variable that is being tested is called the independent variable, and it is directly manipulated by a scientist. The rest of the variables need to remain unchanged in order not to get wrong results like the scientist in the given scenario.

As the scientist is trying to see how gamma rays affect marigolds, only the gamma ray exposure is supposed to change throughout the experiment. The amount of water remained the same, but the number of hours of sunlight didn't. That's why we don't know what exactly affected the growth of marigolds - the sunlight or the gamma rays? And that's why the scientist's conclusion is flawed.

Scout fought Walter Cunningham because *

Answer: Scout fought Walter Cunningham because she blamed him for being punished on the first day of school.

Explanation:

Jean Louse Finch, known under the nickname "Scout", is a young girl, and a character from Harper Lee's novel, <em>To Kill a Mockingbird</em>.

At the beginning of <em>Chapter 3</em>, it is the first day of school, and the teacher criticizes Scout's father for teaching her how to read. Scout is upset by the teacher's criticism, but the situation becomes even worse later, when the teacher offers Walter Cunningham money for lunch. Scout, aware of the financial situation of the Cunningham family, explains to the teacher that Walter never borrows money, because he cannot pay back. As a result of Scout's behavior (which the teacher considers inappropriate), Scout is punished and her hand is smacked. Scout, clearly angry and frustrated, blames Walter for her bad day, and decides to "rub his nose in the dirt."
