In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar., a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame.

Answers

The answer is definitely C, it is the grammatical way to form the sentence.

I want to go to the yard sale; I heard there are some great deals is making this sentence correct. Hence, option C is correct.

What is meant by sale?

A sale is an agreement wherein two or more people trade goods or services for money or other resources. The word "sale," which also comes in the expressions "for sale" and "on sale," implies a trade at a reduced cost.

When employed as a verb, sell means promoting or persuading someone to purchase a certain good or service. It also means giving something away in exchange for money.

A price reduction or the selling of goods or services are both considered sales. Selling a new house serves as an example of a sale. An example of a sale is a store offering all jeans at a 50% discount. A real estate transaction where the highest bidder wins.

Thus,  option C is correct.

"A Satirical Elegy on the Death of a Late Famous General" written by Jonathan Swift speaks about the life and death of a dishonourable and deceased duke.

In the poem, the speaker actually reveals his true feelings about the person. He shows that though he was dead yet people still felt the stink and sting of his influence in their lives. Mourners were not found at his funeral. His wealth and achievements were worthless.
