There is an experiment for this, or at least an observation, make long ago by Karl Von Frisch and more recently confirmed by James Gould at Princeton, Biologists who wish to study such things as bee navigation, language, and behavior. in general have to train their bees to fly from the hive to one or another special place. To do this, they begin by placing a source of sugar very close to the hive so that the bees (considered by their trainers to be very dumb beasts) can learn what the game is about. Then, at regular intervals, the dish or whatever is moved progressively father and farther from the hive in increments (增长) of about 25 percent at each move. Eventually, the target is being moved 100 feet or more at a jump, very far from the hive. Sooner or later, while this process is going on, the biologists shifting the dish of sugar will find the bees are out there waiting for them, precisely where the next position had been planned. This is an uncomfortable observation to make.
With what subject is the passage mainly concerned？
A．The bee, a social animal.
B．Navigational techniques of bees.
C．Testing the awareness of bees.
D．The bee hive, nature's candy shop.

The marvel of the machine age, the electronic computer has been in use only since 1946. It can do simple computations—add, subtract, multiply, and divide—with lightning speed and perfect accuracy. It can multiply two 10-digit numbers in 1/1, 000 second, a problem that would take an average person five minutes to do with pencil and paper. Some computers can work 500, 000 times faster than any person can.
Once it is given a program, that is, a carefully worked-out set of instructions devised by a technician trained in computer language, a computer can gather a wide range of information for many purposes. For the scientist it can get information from outer space or from the depths of the ocean. In business and industry the computer prepares factory inventories, keeps track of sales trends and production needs, mails dividend checks, and makes out company payrolls. It can keep bank accounts up to date and make out electric bills. If you are planning a trip by plane, the computer will find out what route to take and what space is available.
Why does the author regard the electronic computer as the marvel of the machine age？
A．Because electronic computers are rare.
B．Because people know little about electronic computers.
C．Because electronic computers can do much more kinds of work that human beings can't.
D．Because electronic computers have been widely suspected.
Production and sales from the new machine are expected to be 100,000 units per year. Each unit can be sold for $16 per unit and will incur variable costs of $11 per unit. Incremental fixed costs arising from the operation of the machine will be $160,000 per year.
Warden Co has an after-tax cost of capital of 11% which it uses as a discount rate in investment appraisal. The company pays profit tax one year in arrears at an annual rate of 30% per year. Capital allowances and inflation should be ignored.
Required:
(a) Calculate the net present value of investing in the new machine and advise whether the investment is financially acceptable. (7 marks)
(b) Calculate the internal rate of return of investing in the new machine and advise whether the investment is financially acceptable. (4 marks)
(c) (i) Explain briefly the meaning of the term ‘sensitivity analysis’ in the context of investment appraisal; (1 mark) (ii) Calculate the sensitivity of the investment in the new machine to a change in selling price and to a change in discount rate, and comment on your findings. (6 marks)
(d) Discuss the nature and causes of the problem of capital rationing in the context of investment appraisal, and explain how this problem can be overcome in reaching the optimal investment decision for a company. (7 marks)
