There are several helpful models of what this important period actually looks like for language.  d. It was first developed by early educators such as Dr. Maria Montessori, though she referred to it as a “sensitive period.”  acquisition.  e. It designates the time in one’s life during which the capacity to absorb the rules and structure of a language is maximized."

It is also important that you provide sentence 5 of the text. Sentence 5 is:

<em>"Boston-area researchers found evidence that the time span for language acquisition lasts from infancy  until early adulthood; this time span is known as the “critical period.” </em>

Answer:

e. It designates the time in one’s life during which the capacity to absorb the rules and structure of a language is maximized.

Explanation:

The text shows that there is a gradual process that allows the human being to acquire language clearly and effectively. This process goes through a period of time known as "critical performer". Phrase 6, relates this period to the amount of time it takes for an individual to develop his vision and be able to interpret and understand what he saw, being able to transmit through language.
