Step 1: Understanding the Concept:
The sentence contains an error in the choice of word form (parts of speech). We need to identify and correct it.

Solution (for ii):
Step 1: Understanding the Concept:
This sentence has a preposition error. The choice of preposition after the verb 'died' depends on the cause of death.
Step 2: Detailed Explanation:
The correct preposition to use for death caused by a disease, illness, hunger, or thirst is 'of'. The preposition 'from' is typically used for death caused by an external factor like a wound, an accident, or overeating. Since 'cancer' is a disease, the correct preposition is 'of'.
Corrected Sentence: He died of cancer.
