Today while reading the newspaper I found two sentences with the opposite pattern of tense usage.
Sentence 1 (Indirect speech) : A senior police officer said that the cumulative rents paid for some of these buildings are enough to purchase a land and build a police station.
The direct speech must have been like this - A senior police officer said, "The cumulative rents paid for some of these buildings are enough to purchase a land and build a police station".
Sentence 2 (Indirect speech) : The girl said that she wanted some ice water.
The direct speech must have been like this - The girl said, "I want some ice water".
My query was, why in sentence 1 'are' was not changed to 'were' although in sentence 2 'want' was changed to 'wanted' because in school we were taught that while converting direct speech to indirect speech, tenses are back shifted.
I looked up this query on Google and I learned that even 'are' is also correct in indirect speech of sentence 1. So by this logic, is it correct to use 'want' in indirect speech of sentence 2 ?
Thank you!
