In an experiment, researchers posed simple questions in geometry to children from varied backgrounds. One group consisted of 7-to-13-year-old children of the Mundurucu, an isolated indigenous group in the Amazon basin. The Mundurucu children, who had no formal training in geometry, answered the questions just as quickly and accurately as did French chidlren of the same ages who did have formal training in geometry. In contrast, 5-year-old North American children had much more trouble answering the questions. The researchers concluded that some basic geometric knowledge is innate, but this innate knowledge typically develops only after age 5.
In the table, select the statement that would, if true, most strengthen the researchers' conclusion and most weaken it, respectively. Make only two selections, one in each column.

Official Explanation
If the researchers had posed the same questions to 5-year-old French and Mundurucú children as they posed to the 7-to-13-year-old children, the results may or may not have corroborated the researchers’ conclusion.
If, however, the Mundurucú children who were 5 years old had the same difficulty in answering the questions as their North American counterparts, then the researchers would have further evidence that the ability is not present in children under the age of 5 but appears to develop thereafter.
The correct answer is Mundurucú children who were 5 years old had just as much trouble answering the questions as did the 5-year-old North American children.
If it were true that North American children 7 to 13 years old had much more trouble answering the questions than did the Mundurucú of the same ages, then this would provide some evidence that the ability is not innate.
The correct answer is North American children 7 to 13 years old had much more trouble answering the questions than did the Mundurucú of the same ages.

Most strengthen: Mundurucu children who were 5 years old had just as much trouble answering the questions as did the 5-year-old North American children,since if Mundurucu children also faced difficulty that actually strengthens the claim that innate knowledge develops after 5.
Most weaken: North American children 7 to 13 years old had much more trouble answering the questions than did the Mundurucu of the same ages,this point weakens the claim since North American students are weaker than Mundurucu children so the claim related to age is weakened
