Which details can be considered primary support for the main primary suppor for the main idea statement.

The development of speech in infants follows a definite sequence or pattern of development.

a.By the time an infant is six months old, he or she can make 12 different speech sounds.
b.Before the age of three months, most infants are unable to produce any recognizable syllables
c.During the first year, the number of vowel sounds a child can produce is greater then he or she can make
d.During the second year, the number of consonant sounds a child can produce increases
e.Parents often reward the first recognizable word a child produces by smiling or speaking to the child

I put B, C, D,

The primary support details for the main idea statement "The development of speech in infants follows a definite sequence or pattern of development" are:

b. Before the age of three months, most infants are unable to produce any recognizable syllables.
c. During the first year, the number of vowel sounds a child can produce is greater than he or she can make.
d. During the second year, the number of consonant sounds a child can produce increases.

To determine which details can be considered primary support for the main idea statement, you need to identify the details that directly support or explain the main idea.

The main idea statement in this case is: "The development of speech in infants follows a definite sequence or pattern of development."

Let's break down each option and see if they provide primary support:

a. "By the time an infant is six months old, he or she can make 12 different speech sounds."
This statement provides some information about the development of speech sounds but does not necessarily support the idea of a definite sequence or pattern of development. So, it is not a primary support.

b. "Before the age of three months, most infants are unable to produce any recognizable syllables."
This statement directly supports the main idea by showcasing the early stage of speech development where infants are unable to produce recognizable syllables. It provides evidence of a sequence or pattern of development. Thus, it can be considered primary support.

c. "During the first year, the number of vowel sounds a child can produce is greater than he or she can make."
This statement also supports the main idea by highlighting the progression in speech development, specifically related to vowel sounds. It adds further evidence to the sequence or pattern of development, so it can be considered primary support.

d. "During the second year, the number of consonant sounds a child can produce increases."
Similar to option c, this statement supports the main idea by emphasizing the increase in consonant sounds during the second year. It adds additional evidence of a sequence or pattern of development, so it can be considered primary support.

e. "Parents often reward the first recognizable word a child produces by smiling or speaking to the child."
Although this statement provides information about parents' reactions to a child's speech development, it does not directly support the main idea of a definite sequence or pattern. Therefore, it is not primary support.

Based on this analysis, options b, c, and d can be considered primary support for the main idea statement.
