Directions: The sentence is underlined in three separate parts and each one is labelled (a), (b) and (c). Read the sentence to find out whether there is an error in any underlined part. If there is no error, you may signify a ‘No error’ response.

(a) The problem (b) was so difficult (c) to be resolved. (d) No error

The error is in part (b). So difficult is wrong. It should be too difficult. This comes under the category of transformation of sentences (remove too). In sentences containing adverb too, the transformation is done as under: The problem was too difficult to be resolved. The problem was so difficult that it could not be resolved.
