Adjective
I found this sentence and I think something is wrong.
"Laos has a land area comparable to that of Great Britain but a population of only four million people, many of whom are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north."
I found "a land area comparable to" is awkward, because "a land area" is noun and "comparable" is adjective. I think it should be "a land area which is comparable to".
Is there minor grammatical rule going on here??
Is something hidden between "a land area" and "comparable"??
I appreciate any kinds of your answers.
Thank you :)
