In an experiment, one thousand nine-year-old children were allowed to choose whether to participate in a program in which the researchers taught them dance during the daily break from their lessons. Four hundred of the children chose to participate for at least one year. At the end of the year, researchers found that the children who had participated had significantly better balance, on average, than those who had not. The researchers hypothesized that dancing resulted in a sustained improvement in the children’s sense of balance.It would be most helpful in evaluating the researcher’s hypothesis to know whether the researchers ___1___ prior to having ___2___.
Select Researchers for the phrase that fills the blank labeled 1 in the given statement, and select Prior to for the phrase that fills the blank labeled 2 in the given statement to create the most accurate statement on the basis of the information provided. Make only two selections, one in each column.

RO1, Researchers and RO2, Prior to having:
Note that because of the relationship between the two answers that complete the sentence, the responses have to be considered together, not separately.
The question asks what would be most helpful to know when evaluating the researchers’ hypothesis. To answer this, it is useful to consider what some alternative explanations for the better balance of the children who had participated in the program. One alternative would be that the children who had decided to participate in the program already had better balance before participating. Therefore, it would be useful to know whether they actually did have any improvement in their balance. To resolve that issue, it would be helpful if we knew that the researchers had this information, which they could have acquired by testing the children’s sense of balance prior to teaching them dance through the dance program.
The correct answer to RO1 is tested the children’s sense of balance.
The correct answer to RO2 is taught dance to the children through the dance program.

1. We want to pick two statements to complete the sentence in order to strengthen the hypothesis.
2. The hypothesis is that balance in children improved thanks to dance.
3. The opposite of the hypothesis is that it didn't. This would mean that the kids who chose to be in a dancing program, where already more skilled in balance.
4. To counter this, the researchers would need to check the children's balance before the program.
5. The two best statements that together match this are: 1 - tested the children’s sense of balance and 2 - taught dance to the children through the dance program.
