The answer is b) delicate
(I'm assuming these sentences are all in past context)
1. He failed because he did not listen to the advice of his teacher.
(Adding did will maintain the past tense of the sentence)
2. He learnt that he was ill but could not go to see him.
(Changing be to was maintains the past tense. Could is past tense as can is present tense)
3. He said that he came to our house to discuss the matter.
(Came is past tense as come is present tense)
In reality, these laws passed by government were only helpful to the government members since most of them were landowners. They wanted to earn more (money made/good thing received) from increased corn prices and not having to buy corn which they can help grow on (more than needed) land and sell it themselves. However, since most of the old England lived in cities, they had no land to grow the vegetable and depended on buying products (that are bought and sold). This is why (related to elected lawmakers) (people in charge of something) were unwilling to revise the law.
In 1828, the Duke of Wellington's government changed/redone the Corn Laws and they made a sliding scale for the weight-to-price of the corn. This rewriting/redoing still did not help the residents of old England since the price was still high.
