Read the sentence to find out whether there is any error in it or not. The error, if any, will be in one part of the sentence. The number of that part (which has the error) is the answer. If there is no error, the answer is (5). Ignore errors of punctuation, if any.
Pablo Picasso showed (1)/ his truly exception (2)/ talent from (3)/ a very young age. (4)/ No error (5).
Correct option - 2
Here, concept of adjective is brought under consideration. Since, truly is an adverb, an adverb is a word or phrase that modifies the meaning of an adjective, verb, or other adverb, expressing manner, place, time, or degree (e.g. gently, here, now, very). But, exception is a noun and an adverb is not used before noun. Also, talent is a noun. We know adjective is used before noun. Hence, in order to make 'exception' an adjective, replace exception with exceptional. Thus, option 2 has grammatical error. So, option 2 is the correct answer.
Correct sentence - Pablo Picasso showed his truly exceptional talent from a very young age.
