Question

many studies have indicated that multilingual people—people who speak more than one language—are better at certain tasks. specifically, multilingual people have better executive functioning skills than people who speak only one language. executive functioning is the way the brain handles all the information it’s given. when you juggle different tasks and decide which to focus on, you are using executive functioning skills. in brain scans, multilingual people show more blood flow in the areas of the brain that control executive functioning. researchers have guessed that this advantage exists because multilingual people must constantly decide which words from which language to use. as a result, multilingual people get lots of practice with executive function. their brains can then apply those skills to other tasks. this effect is especially strong for people who grow up speaking more select the evidence that the author provides for the following claim: people who speak more than one language have better executive function. research shows that people’s executive function improves after foreign language classes. the brain scans of multilingual people show more blood flow in areas associated with executive function. a study showed that multilingual people are distracted more easily.

Explanation:

The claim is that multilingual people (who speak more than one language) have better executive function. We analyze each option:

• Option 1: Research on executive function improvement after foreign language classes doesn't directly support the claim about multilingual people (speaking more than one language) having better executive function. It's about improvement after classes, not comparing multilingual vs. monolingual.
• Option 2: Brain scans of multilingual people showing more blood flow in areas associated with executive function directly supports the claim. The passage states "In brain scans, multilingual people show more blood flow in the areas of the brain that control executive functioning", so this evidence matches.
• Option 3: A study showing multilingual people are distracted more easily is not relevant to supporting better executive function; it would be a counter - argument if anything.

Answer:

The evidence that supports the claim is: The brain scans of multilingual people show more blood flow in areas associated with executive function. (Corresponding to the second option in the given choices)
