General Fabricators assembles its product in several departments. It has two departments that process all units. During October, the beginning work in process in the cutting department was half completed as to conversion, and complete as to direct materials. The beginning inventory included $12,000 for materials and $3,000 for conversion costs. Ending work-in-process inventory in the cutting department was 40% complete. Direct materials are added at the beginning of the process. Beginning work in process in the finishing department was 75% complete as to conversion. Direct materials are added at the end of the process. Beginning inventories included $16,000 for transferred-in costs and $20,000 for conversion costs. Ending inventory was 25% complete. Additional information about the two departments follows: Cutting Finishing Beginning work-in-process units 20,000 20,000 Units started this period 40,000 50,000 Units transferred this period 50,000 Ending work-in-process units 10,000 20,000 Material costs added $48,000 $28,000 Direct manufacturing labor $16,000 $40,000 Other conversion costs $8,000 $24,000 Required: Prepare a production cost worksheet using weighted-average for the cutting department and FIFO for the finishing department.

听力原文： If the population of the Earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on Earth will make it necessary for us to look for open space somewhere else.

An American scientist, Professor Cart Sagan, believes that before the earth's resources are completely exhausted, it will be possible to change the atmosphere of Venus and so create a new world almost as large as Earth itself. The difficulty is that Venus is much hotter than the Earth and there is only a tiny mount of water there.

Sagan proposes that algae, an organism that can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be bred in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.

When the algae have done their work, the atmosphere will become cooler but before man can set foot on Venus, it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for men to land on it but the rain will eventually fall and in a few years something like Earth will be reproduced on Venus.

A．The way to ensure the survival of the human race on Venus.

B．The way to breed organisms on Venus.

C．The way to reduce the population of the Earth.

D．The way to conquer the universe.
