Normally experts say
estimated at should be followed by an noun
e.g: the temperature is estimated at negative five hundred degrees
and estimated to be should be followed by non nouns(such as adjectives)
e.g the fossil is estimated to be 500 years old
THEN WHY ARE WE CHOOSING E OVER C?

Quote:
* "at" is a preposition.
* prepositions must be followed by nouns.
* "xxx number of years old" is not a noun.
so, wrong.

in the other example -- "temperatures estimated at xxxx degrees fahrenheit" -- there's no problem, because "xxxx degrees fahrenheit" is a noun.

i don't think anything else is happening here.
the OG explanations are wrong fairly regularly (though not in most cases); this is one of those times.


This is what Ron Purewal of Manhattan GMAT has to say about estimated at/to be scenario
Shouldn't the same logic apply to dated at/dated to be as well?

i know it gives E
I am asking why!!
Why the discrepancy between estimated to be and dated to be?


souvik, the link, discussion at MGMAT, conveys answer to be C!
your OG answer says E !

the discrepancy is in two answers ..
unless we know which one is correct - let have some expert comment,
then only it is relevant to discuss 'estimated to be/dated to be ..'

the only difference between (c) and (e) is idiomatic expression.
you don't say "dated to be..."; you do say "dated at...".

like other idiomatic expressions, this is one of those things that doesn't go according to any sort of logical rule; you just have to know it.
you should dedicate a page or two of a notebook to this, or make some flash cards for the ones you don't know.


This is what Ron has to say about DATED AT & DATED TO BE.

The rule is applicable with other expression with other expressions like ESTIMATED or ESTIMATED TO BE.

din get what you said
Ron said that estimated at should be followed by a noun
for other cases we use estimated to be
and og says dated to be 300 million years old.
this is my confusion.

Ok...He says..
'Estimated at' should be followed by a noun because it follows a preposition 'at' which always takes Noun. Eg. This monument is estimated at 300 mn years.
If we say 'This monument is estimated at 300 mn years old' then its wrong because '300 mn year old' is an adjective whereas '300 mn year' is noun.

In any case if we have to use '300 mn years old', we'll say 'This monument is estimated to be 300 mn years old'.

He further says this rule is not applicable to 'Dated at' and 'Dated to be' because 'Dated to be' is non idiomatic..It doesn't work, I means natives do not use 'dated to be' anywhere. Hence 'Dated to be' is always wrong irrespective of what it follows (a noun or an adjective).

HTH

Re: Rock samples taken from the remains of an asteroid about [#permalink] New post 27 Dec 2012, 21:57
I picked C because I thought

"to be" is the correct idiom.

I swear to god I saw in the OG somewhere else say that the correct idiom is

"estimated to be"

But apparently when the word is "dated" it should be

"dated at"

according to the explanation given for this question

can anyone provide some definitive clarity here?
