Question

while researching a topic, a student has taken the following notes:

• the \lost - wax\ process is a method for creating detailed metal sculptures that dates back over 5,000 years.
• the process begins with a core model made of clay, which is then covered with a thin layer of beeswax.
• the artist carves intricate details into the wax layer, as this will determine the final appearance of the metal.
• the wax model is then encased in a thick outer mold made of heat - resistant material, such as clay or plaster.
• when the mold is heated, the wax melts and drains out through small holes, leaving a hollow space (the \lost\ wax).
• molten metal is poured into this cavity; once cooled, the outer mold is broken away to reveal the finished bronze or gold piece.

the student wants to summarize the process of lost - wax casting. which choice most effectively uses relevant information from the notes to accomplish this goal?
a lost - wax casting is an ancient metallurgical technique used for over 5,000 years to create bronze and gold sculptures.
b in lost - wax casting, a metal sculpture is created by pouring molten metal into a hollow space left behind after a carved wax layer is melted out of a heat - resistant mold.
c the artist must first create a clay core and cover it in beeswax because the wax allows for much more intricate carving than metal or clay.
d the final step of the lost - wax process involves breaking away the thick outer mold of clay or plaster to reveal the cooled metal sculpture inside.

Explanation:

To summarize the lost - wax casting process, we need to include the key steps. Option A only mentions the age and materials for sculptures, not the process. Option C focuses on why wax is used, not the process. Option D only talks about the final step. Option B describes the process: creating a wax - carved layer, melting the wax out of a heat - resistant mold, and then pouring molten metal into the hollow space, which covers the main steps of lost - wax casting.

Answer:

B. In lost - wax casting, a metal sculpture is created by pouring molten metal into a hollow space left behind after a carved wax layer is melted out of a heat - resistant mold.
