Every child in a certain family has been diagnosed with autism spectrum disorder (ASD). Based on this evidence, what possible conclusion can be drawn about ASD?

A. ASD may be lethal.

B. ASD may be genetic.

C. ASD is related to traditional nuclear family structures,

D. No conclusion can be drawn based on this evidence.

Answer Explanation:

The evidence says that every child in a certain family has been diagnosed with autism spectrum disorder (ASD). All of these children have genetic commonalities. Therefore, ASD may be genetic.

The evidence does not mention whether the children died from ASD. Therefore, no conclusion can be drawn that ASD may be lethal. Furthermore, the sample size of the evidence is much too small to suggest that ASD is related to traditional nuclear family structures.

Therefore, the Correct Answer is B.

Q #1: Which of the below is the best definition for the term circulation?

A. The transport of oxygen and other nutrients to the tissues via the cardiovascular system

B. The force exerted by blood against a unit area of the blood vessel walls

C. The branching air passageways inside the lungs

D. The process of breathing in

Circulation is transporting oxygen and other nutrients to the tissues via the cardiovascular system. Choice B refers to blood pressure. Bronchi are the branching airways inside the lungs, while inhalation refers to the process of breathing in.
Q #2: Given that there are over 100 million residential addresses in the United States, which of the following best describes a flaw of this survey as it is described?

A. There were not enough age groups to show a trend based on age.

B. The addresses were chosen randomly rather than strategically

C. The distribution of ages in the sample did not reflect the actual population

D. Each response represents only one person per address

Answer Explanation

While the random selection and large number of surveys sent out were a good start, to truly study the relationship between age and screen usage, it would have been better to have a few more age groups or just a direct age value from each participant rather than four large categories. As far as whether the age distribution accurately reflected the population, we don't have enough information to say if that was a problem or not. Also, the fact that each response is from just one person at the address is not a flaw but a reasonable way to get a good variety of responses
Q #3: Which of the following is a carbohydrate?

A. Cellulose

B. Hemoglobin

C. Estrogen

D. ATP

Answer Explanation
