1. Most never ask ourselves if and how television might hurting us.

(Do we have to use 'ourselves'? How about 'themselves' in place of 'ourselves'?)

2. Below you will find the costs and benefits of watching television.
(Does 'costs' mean
'disadvantages' here?)

3. Some blame "the" television for society's violence, consumerism, and misinformation.
(Do we have to put 'the'
before 'television'? What about deleting 'the'?)

1. You would use "ourselves" only if the subject were "We" but since the subject here is "Most" then "themselves" is correct.

2. Yes, costs are what we PAY and benefits are the good things we RECEIVE from whatever the sentence is about. So, yes, costs could mean disadvantages in this context.

3. You can either keep or omit "the" before "television" in this sentence. Either way works fine.

1. In the sentence, "Most never ask ourselves if and how television might be hurting us," the use of "ourselves" implies that we are referring to the act of introspection or self-reflection by the speaker or the group they are a part of. If you use "themselves" instead, it would shift the focus to a more general statement, indicating that people, in general, do not ask if and how television might be hurting them. This change would make the statement more inclusive and less personal.

2. In the sentence, "Below you will find the costs and benefits of watching television," the word "costs" does imply disadvantages. In this context, "costs" refers to the negative aspects or drawbacks of watching television, such as time spent, potential health concerns, or negative influences. The term "benefits," on the other hand, refers to the positive aspects or advantages of watching television, such as entertainment, educational content, or relaxation.

3. In the sentence, "Some blame 'the' television for society's violence, consumerism, and misinformation," the use of "the" before "television" is optional. Including "the" is grammatically correct and commonly used, but excluding it is also acceptable. Both versions convey a similar meaning, suggesting that television as a whole is being held accountable for society's issues. The choice of including or excluding "the" would work depending on the author's personal preference or writing style.
