Good Question. What is the source?

"not unlike" - 2 negatives makes it positive. So, its basically saying 'like'

Now, what is being compared? Jackie Robinson's courage is being compared to the courage of Rosa Parks.

'Like' should be used to show similarity & 'as' is used to compare 2 nouns performing 2 actions. This this case, 'like' is the correct usage. So, E is out.

A- Correct comparison
B - Wrong comparison. Courage of Jackie Robinson is being compared to Rosa Parks.
C - Wrong comparison & awkward construction
D - Awkward construction

A. correct as compares apples to apples. courage of JR compared to courage of Rosa. "who refused" correct modifies Rosa

B. compares "courage" of JR to Rosa Parks herself hence incorrect

C. likens "courage" of JR to Rosa Parks+her refusal, hence incorrect

D. Rosa Park's courage for refusing does not make sense

E. uses "as" to compare courage which is a noun. "as" normally compares clauses and "like" compares nouns.

'

Like' should be used to show similarity & 'as' is used to compare 2 nouns performing 2 actions. This this case, 'like' is the correct usage. So, E is out.

Don't you think we should use as to compare courage rather than Like

I think Like is used to compare Nouns and as is used to compare abstract entities.

Thanks

I believe 'courage' in this sentence is a noun and hence the use of 'like'

I thought courage is a quality and hence adjective.Please correct me if this is wrong!

@vemuri

The source is OG-10

courage is a noun. courageous is the adjective form

Thanks for clearing my doubt.
I thought Courage is adjective...
