Questions I to 3 are based on the statements from Animal Liberation and The Royal Society for the Prevention of Cruelty to Animals below.

UNIT 2

Questions 4 - 6

One way of conserving water is to collect rainwater from roofs of houses to use for drinking.

However, after a period without rain, the first rainwater washed from a roof into a storage tank

may be contaminated with dirt.

One device used to overcome this problem is illustrated in the figure. The bent pipe delivering

water from the roof to the storage tank has a vertical extension (the device) containing a ball

that floats on water. At the bottom of the device is an outlet tap.

Question 4

How does the device attempt to solve the problem of the dirty water?

Question 5

Outline two problems related to the design of the device that could stop the device from

functioning properly.

Question 6

Suggest an improvement to the design of the device and explain the value of the changed

design.

UNIT 7

Question 14

Examine the arguments of JM and BL about prisons below.

What arguments are presented?

Which of their arguments are strong and which are weak?

Explain why you find their arguments either strong or weak.

Your responses will be judged on the:

• accuracy with which the views are presented; and

• effectiveness with which the arguments are assessed.

|Should prisons be for rehabilitation or for punishment? |

| |

|JM comments |

|There is no justification to punish the vast majority of people in prison. Most prisoners are in |

|gaol because society has forced them into a position where they have no alternative but to |

|pursue (or are simply unable to avoid) a criminal lifestyle. |

| |

|BL responds |

|No. You can take an anger management course if that's your problem. You can get a job |

|interview if you need money. You can clean up your act, you can go cold turkey, you have a |

|choice. |

| |

|It's a cop out to say that society completely influences people's actions, that the thief doesn't |

|have the ultimate choice to not commit crimes, that the rapist is 'driven' to abuse. We punish |

|people, we take our retribution from them, we want them to suffer to atone for and balance out |

|the evil caused by them. |

| |

|Prisons should only be concerned with rehabilitation in the interests of the honest and law |

|abiding. After we've punished criminals, how do we want them when they are released? We |

|want an overall reduction in crime, not an overall reduction in the amount of suffering endured |

|by those who feel a need to commit it. |

| |

|I personally believe that a major part of punishment is suffering, and that a major part of |

|punishment in our country is prison. I guarantee you that there are more people in prison who |

|deserve what they get than people who don't. |

| |

|JM responds |

|It's easy for us to say "you have a choice", but making the 'right' choice, if you want to call it |

|that, is not so easy. Ever tried going cold turkey from a serious drug addiction? Ever tried |

|growing up in poverty where all around you is nothing but crime and deviance, where everyone |

|is at war against you and your community, and where you're taught from the youngest age that |

|police are the enemy? Go live there and then tell me how easy it is. |

| |

|You want less crime? Then the first thing you want to do is change the way police operate and |

|stop sending so many people to gaol, and change what gaols are like. We see the crime control |

|problem as a 'war', a war against people who commit acts that are labelled 'crimes' and these |

|criminals then become targets in this war. Rather than being subject to severe penalties, these |

|people should be seen as indicators of severe social injustice. |

| |

|And as for gaols, well if you're not a criminal when you go in, you will be by the time you're |

|out. They're simply universities for criminals. |

UNIT 8

Questions 15 – 17

It is claimed that a new product, Growgreat, makes plants grow 20% faster than they normally

do. Growgreat is sold as small water-soluble pills (tablets).

A gardener decides to investigate the claim. Five tests that the gardener considers are

represented in the figure below. The initial conditions of all plants are the same (same size plant,

pot, soil etc.) The growing conditions are the same for each test (same light, same fixed daily

amount of water, same air exposure etc), except for the differences indicated (the Growgreat pill

and water additional to the daily supply).

[pic]

Question 15

What would a comparison of the results of treatments I and II show? Explain

Question 16

In evaluating the claim, how useful would be a comparison of the results of treatments III and

IV? Explain.

Question 17

In order to evaluate the claim, which two tests would provide the most valuable information?

Justify your answer.

UNIT 9

Your responses will be judged on:

• precision with which the ideas are presented; and

• substance and significance of the arguments presented.

Argument 1

Argument 2

Question 19

Argument 2

UNIT 10

Questions 20 - 23

A decrease in ozone in the atmosphere occurred after the introduction of the chemical CFC into

spray cans. The decrease in ozone has been greatest around the north and south poles.

Figure 1 indicates the relationship between percentage ozone decrease and percentage groundlevel

UV-B increase for major Australian cities between 1980 and 1990. UV-B is a form of

radiation from the Sun that causes skin cancer and other health problems. The figure also shows

predictions for the period 1990 to 2005.

[pic]

Question 20

What does Figure 1 show about

• % ozone decrease and the different cities

• % ozone decrease and % UV-B increase

• % ozone decrease and the different time periods shown in the key?

Figure 2 indicates the total amount of UV-B (arbitrary units) that reached the Earth in 1980 for

various latitudes (between 10° and 45° South) on the Australian continent. The numbers on the

contour lines (3000, 2500, 2000, 1500 and 1000) are proportional to the total amount of UV-B

that reached the ground in 1980. At the 3000 contour line, three times as much UV-B radiation

reached the ground as at the 1000 contour line.

[pic]

Question 21

In which of the cities named in Figure 2 did the greatest level of UV-B radiation occur in 1980?

Question 22

What is the predicted increase in UV-B radiation reaching the ground in Hobart between 1990 and 2005 (expressed in the arbitrary units of Figure 2)? Explain your reasoning.

Question 23

A 1990 newspaper article used the information in Figures 1 and 2 to predict that by 2005 the

people of Hobart would have the greatest risk of skin cancer from DV-B in Australia. Evaluate

this statement.

Question 24

What does Jean-Paul Sartre suggest about freedom by the following statement?

Freedom is what you do with what's been done to you.

John-Paul Sartre

UNIT 12

Question 25

Below is an advertisement for a computer. Explain how the text and image of the advertisement

is structured and presented to create an impression and convey a message.

Your responses will be judged on the:

• accuracy of the description or understanding of the material; and

• substance and quality of the interpretation offered.

UNIT 13

Questions 26 – 30

Studies have shown that the height of sea waves is determined by wind-related variables such

as:

1 Fetch - the distance the wind blows over the sea surface.

2 Wind speed - the average speed at which the wind blows.

Table 1 gives the results of a study of the height of waves for various fetches and wind speeds

(when the wind has blown for 24 hours).

[pic]

Answer all questions in this unit according to the information in the table

Question 26

What is the wind speed when the wave height is 13.6 m and the fetch is 1000 km?

Question 27

Estimate the wave height at a wind speed of 90 km/h after a fetch of 1500 km.

Question 28

On Figure 1 below draw a graph line for a fetch of 700 km. The scale is linear on both axes

[pic]

Question 29

Complete labels L1, L2, L3 and L4 on the graph in Figure 2 to show how this graph could

represent some data from Table J. The scale on the graph is linear on both axes

[pic]

Figure 2

Question 30

What do the data in Table 1 show about the relationship between the three variables?
