The statement which states that there is strong empirical support indicating that learning two languages <em>interferes </em>with effective cognitive development and this statement is false.
As a result of this, we can see that cognitive development has to do with the way the brain develops with regards to what it can assimilate things and we can see that there is NO evidence which supports that learning two languages would limit this development.
Therefore, the correct answer is false.

For an accurate measurement of cardiovascular activity, researchers typically: D) measure the number of heartbeats per minute.
<h3>What is cardiac cycle?</h3>
Cardiac cycle is a process that involves the complete heartbeat of the human heart, which comprises sequential alternating contraction and relaxation of the atria and ventricles, so as to cause blood to only flow in one direction throughout the human body during any cardiovascular activity.
As a general, researchers should typically measure the number of heartbeats of a person per minute, so as to ensure an accurate measurement of cardiovascular activity.
