Why does Bruno describe the silence as "noisy" What does he mean by that? Have you ever been in a tense situation where an awkwa
emmainna [20.7K]

Hello. You forgot to add the necessary text to answer this question. The text is:

“There are hundreds of children here…only they’re on the other side of the fence.’ A silence followed this remark, but it wasn’t like a normal silence where it just happens that no one is talking. It was a silence that was very noisy.”

Answer:

Bruno refers to the silence as "noisy" because the silence was able to convey a message.

I did not go through any situation where the silence was awkward and heavy.

Explanation:

When Bruno states that the silence was noisy, he means that although nothing was being said, the silence passed a message and that was not a common message, it was a very clear message, easily understandable and a tense, frightening and negative message.

Situations in which the silence becomes noisy, are uncomfortable, stressful and fearful situations that cause people's anxiety and fear.

Inessa [10]

Check below for answers and explanations

Explanation:

Lucy has previously worked in the library as a high school student before going there for the volunteering service. The experiences she has gotten from her past works in the library will be deployed into her current program for a successful outcome.

b) Alrtruism is a philosophical term that describes the concern of an individual for the well-being of others. Lucy's volunteering service that is targeted at assisting disadvantaged children is a proof of her altruistic lifestyle.

c)The Big five trait of extraversion describes how sociable a personality is. While Lucy was walking in her community library, a good number of children visited, her return to the library to organize a program for children proves that she loves being around and socializing with children.

d) The Broca's area is a part of the brain that plays a vital role in producing and understanding speeches. For Lucy to organize such a developmental program like this, she must be very eloquent with an admirable leadership skills. Her ability to even attend to library users as a high school student is a proof that she has a sound oratory prowess.

e) Self efficacy is the ability to control one's actions and deal with situations that require critical decision making. Lucy's decision to leave a paid job that doesn't give her satisfaction for a volunteering program in the library is an attribute of self efficacy.

f) Episodic memory is the process of bringing back and combining past experiences and events. Lucy recalled how much she enjoyed working at the library and decided to return there.

g) Self actualization is a fulfilment of one's dreams and goals. Lucy's return to the Library is like bringing back the sweet work experiences she once had. This indeed is self actualization.
