Silver stood as one of the surest ways to store wealth at a time before neighborhood banks existed. Unlike the silver coins from which they were made, silver articles were readily identifiable. Often formed to individual specifications, they always carried the silversmith's distinctive markings and consequently could be traced and retrieved.
Customers generally secured the silver for the silver objects they ordered. They saved coins, took them to smiths, and discussed the type of pieces they desired. Silversmiths complied with these requests by melting the money in a small furnace, adding a bit of copper to form. a stronger alloy, and casting the alloy in rectangular blocks. They hammered these ingots to the appropriate thickness by hand, shaped them, and pressed designs into them for adornment. Engraving was also done by hand. In addition to plates and bowls, some customers sought more intricate products, such as silver teapots. These were made by shaping or casting pans separately and then soldering them together.
Colonial coppersmithing also came of age in the early eighteenth century and prospered in northern cities. Copper's ability to conduct heat efficiently and to resist corrosion contributed to its attractiveness. But because it was expensive in colonial America, coppersmiths were never very numerous. Virtually all copper worked by smiths was imported as sheets or obtained by recycling old copper goods. Copper was used for practical items, but it was not admired for its beauty. Coppersmiths employed it to fashion pots and kettles for the home. They shaped it in much the same manner as silver or melted it in a foundry with lead or tin. They also mixed it with zinc to make brass for maritime and scientific instruments.
According to the passage, which of the following eighteenth-century developments had a strong impact on silversmiths？
A．A decrease in the cost of silver.
B．The invention of heat efficient furnaces.
C．The growing economic prosperity of colonial merchants.
D．The development of new tools used to shape silver.

W: Why don't you try house-sitting？ Last summer Cindy was a house sitter for the Smiths when they went away on vacation. They hired Cindy to stay in their house because they didn't want it left empty.
M: You mean they paid Cindy just to live in their house？
W: It wasn't that easy. She had to water the house plants, mow the lawn, and even take care of the pets.
M: I guess it is a little like baby-sitting, except you're taking care of a house instead of children.
W: The student employment office still has a few jobs posted.
M: Do I just have to fill oat an application？
W: You have to have an interview with the homeowner and provide three references at least.
M: That seems like a lot of trouble for a summer job.
W: Well, the homeowner wants some guarantee that they can trust the house sitter. You know they want to make sure you're not the type who'll hold wild parties in their house, or bring a group of friends in with you.
M: I see. House sitters who do that sort of thing probably aren't paid then.
W: Usually they're paid anyway just because the homeowners don't want to make a fuss. But if the homeowner reports it, the house sitter won't be able to get another job easily. So why don't you apply？
M: I think I will. Thank you.
