composed of agricultural and mining wastes. About 3 percent is from industrial wastes. 250 million tons of garbage and refuse come out from homes, schools, office buildings, stores and hospitals.

This mass of metals, paper, food, plastic, rubber and glass which is all mixed together seems of no earthly use to anyone.

Or is it？ Scattered efforts across the country indicate that new technology, properly applied, might someday turn these millions of tons of refuse into an excellent source of raw materials for new uses.

Several new projects are carried out to study the possibility of treating wastes through pyrolysis (高温分解)--a system of reducing refuse to basic chemicals, liquids and gases which have commercial value. In Florida, a special tube system provides automatic transport of refuse to a central collection building.

In short, many new ideas are being tested, and many will be needed, since no one method is likely to prove suitable everywhere.

However, many difficult economic and social questions must be answered before real progress can be made. Can recovered materials compete with new materials？ What will be needed as encouragement to make resource recovery work？ Will citizens pay the costs of changing our waste system？

The article suggests that garbage and refuse from homes and public places ______.

A．make up the largest percentage of solid wastes

B．make up a small percentage of solid wastes

C．are not really considered in the solid waste problem

D．are considered of no use to the earth

2 The Rubber Group (TRG) manufactures and sells a number of rubber-based products. Its strategic focus is channelled

through profit centres which sell products transferred from production divisions that are operated as cost centres. The

profit centres are the primary value-adding part of the business, where commercial profit centre managers are

responsible for the generation of a contribution margin sufficient to earn the target return of TRG. The target return is

calculated after allowing for the sum of the agreed budgeted cost of production at production divisions, plus the cost

of marketing, selling and distribution costs and central services costs.

The Bettamould Division is part of TRG and manufactures moulded products that it transfers to profit centres at an

agreed cost per tonne. The agreed cost per tonne is set following discussion between management of the Bettamould

Division and senior management of TRG.

The following information relates to the agreed budget for the Bettamould Division for the year ending 30 June 2009:

(1) The budgeted output of moulded products to be transferred to profit centres is 100,000 tonnes. The budgeted

transfer cost has been agreed on a two-part basis as follows:

(i) A standard variable cost of $200 per tonne of moulded products;

(ii) A lump sum annual charge of $50,000,000 in respect of fixed costs, which is charged to profit centres, at

$500 per tonne of moulded products.

(2) Budgeted standard variable costs (as quoted in 1 above) have been set after incorporating each of the following:

(i) A provision in respect of processing losses amounting to 15% of material inputs. Materials are sourced on

a JIT basis from chosen suppliers who have been used for some years. It is felt that the 15% level of losses

is necessary because the ageing of the machinery will lead to a reduction in the efficiency of output levels.

(ii) A provision in respect of machine idle time amounting to 5%. This is incorporated into variable machine

costs. The idle time allowance is held at the 5% level partly through elements of ‘real-time’ maintenance

undertaken by the machine operating teams as part of their job specification.

(3) Quality checks are carried out on a daily basis on 25% of throughput tonnes of moulded products.

(4) All employees and management have contracts based on fixed annual salary agreements. In addition, a bonus

of 5% of salary is payable as long as the budgeted output of 100,000 tonnes has been achieved;

(5) Additional information relating to the points in (2) above (but NOT included in the budget for the year ending

30 June 2009) is as follows:

(i) There is evidence that materials of an equivalent specification could be sourced for 40% of the annual

requirement at the Bettamould Division, from another division within TRG which has spare capacity.

(ii) There is evidence that a move to machine maintenance being outsourced from a specialist company could

help reduce machine idle time and hence allow the possibility of annual output in excess of 100,000 tonnes

of moulded products.

(iii) It is thought that the current level of quality checks (25% of throughput on a daily basis) is vital, although

current evidence shows that some competitor companies are able to achieve consistent acceptable quality

with a quality check level of only 10% of throughput on a daily basis.

The directors of TRG have decided to investigate claims relating to the use of budgeting within organisations which

have featured in recent literature. A summary of relevant points from the literature is contained in the following

statement:

‘The use of budgets as part of a ‘performance contract’ between an organisation and its managers may be seen as a

practice that causes management action which might lead to the following problems:

(a) Meeting only the lowest targets

(b) Using more resources than necessary

(c) Making the bonus – whatever it takes

(d) Competing against other divisions, business units and departments

(e) Ensuring that what is in the budget is spent

(f) Providing inaccurate forecasts

(g) Meeting the target, but not beating it

(h) Avoiding risks.’

Required:

(a) Explain the nature of any SIX of the eight problems listed above relating to the use of budgeting;
