Farmer Brown was observing the mice that live in his field. He discovered that all of them were either fat or thin. Also, all of them had either black tails or white tails. This made him wonder if there might be a link between the size of the mice and the color of their tails. So he captured all of the mice in one part of his field and observed them. Below are the mice that he captured Is there a link between the size of the mice and the color of their tails?
Correct answer: B. appears to be a link
- A. appears not to be a link
- B. appears to be a link
- C. cannot make a reasonable guess
- D. The size causes the tail color to change
Explanation
With very few exceptions, fat mice usually have black tails and small mice had white tails. However, this relationship is not enough to establish causality

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.

Isomers are molecules or polyatomic ions with identical molecular formula - that is, same number of atoms of each element - but distinct arrangements of atoms in space. Isomerism refers to the existence or possibility of isomers. Isomers do not necessarily share similar chemical or physical properties. Two main forms of isomerism are structural or constitutional isomerism, in which bonds between the atoms differ; and stereoisomerism or spatial isomerism, in which the bonds are the same but the relative positions of the atoms differ. How many chain isomers can an aliphatic saturated hydrocarbon with 7 carbons make?
