Nouns used as adjectives

@mohankumarbd


Oh! Plenty. However, there is no need to worry, as a word is more relevant for the role it playsand in addition, a word can play only one role in any given context,

I will give you some examples from OG and GPREP. One might see that they hardly interfere.

OG

1. The Glass House Mountains in Queensland, Australia,
Were sighted in 1770 by the English navigator Captain
James Cook,

2. Although a surge in retail sales have raised hopes that
there is a recovery finally under way

Although various eighteenth- and nineteenth-century American poets had professed an interest.

GPREP

The new image of Stone Age people as systematic

There are hopeful signs that we are shifting away from our heavy reliance on fossil fuels:

more than ten times as much energy is generated through wind power now than it was in 1990

In anumber of cases, you will find this example of nouns acting adjectives. But this has never been tested in GMAT as far as I know. I hope this was what you wanted or I am wondering whether I have mistaken your query?
