Answer:
a. a(b)c
b. a(a(b)c)c
d. a(a(a(a)c)c)c
Step-by-step explanation:
We are given the following in the question:
![a,b,c \in W\\\text{If } x \in W \Rightarrow a(x)c \in W](https://tex.z-dn.net/?f=a%2Cb%2Cc%20%5Cin%20W%5C%5C%5Ctext%7BIf%20%7D%20x%20%5Cin%20W%20%5CRightarrow%20a%28x%29c%20%5Cin%20W)
a. a(b)c
It is given b belongs to W.
![b \in W\\\Rightarrow a(b)c \in W](https://tex.z-dn.net/?f=b%20%5Cin%20W%5C%5C%5CRightarrow%20a%28b%29c%20%5Cin%20W)
b. a(a(b)c)c
![a(b)c \in W\\\Rightarrow a(a(b)c)c \in W](https://tex.z-dn.net/?f=a%28b%29c%20%5Cin%20W%5C%5C%5CRightarrow%20a%28a%28b%29c%29c%20%5Cin%20W)
c. a(abc)c
a(abc)c does not belong to W because we cannot find x in W such that a(abc)c belongs to W.
d. a(a(a(a)c)c)c
![a \in W\\\Rightarrow a(a)c \in W\\\Rightarrow a(a(a)c)c \in W\\\Rightarrow a(a(a(a)c)c)c](https://tex.z-dn.net/?f=a%20%5Cin%20W%5C%5C%5CRightarrow%20a%28a%29c%20%5Cin%20W%5C%5C%5CRightarrow%20a%28a%28a%29c%29c%20%5Cin%20W%5C%5C%5CRightarrow%20a%28a%28a%28a%29c%29c%29c)
e. a(aacc)c
a(aacc)c does not belong to W because we cannot find x in W such that a(aacc)c belongs to W.

<h3>What is a comprehension passage?</h3>
In a comprehension passage, some questions are given that follow the passage. The questions are to be answered by using the data given in the passage, even if it differs from real-life facts.
Now,
- Both the given passages use adjectives like 'magnificent' and 'famous' with respect to Martin Luther King's "I Have a Dream Speech".
- The first passage claims, "Many people can still remember the first time they heard I Have a Dream, and they tend to speak of that memory with the reverence reserved for a religious experience."
- While the second concurs with, "For most Americans, those words capture Kings unique genius. They express his immortal longing for freedom, a longing that is familiar to every person who dares imagine a future beyond unjust laws and unfair customs. The edifying universality of those four words who hasn't dreamed, and who cannot identify with people whose dreams of a better world are punished with violence helps to explain their durability."
- In this context, we can deduce that King's I Had A Dream Speech had a profound impact on Americans, i.e., option C is correct.
