Question 1a

Read the following passage from a newspaper report and then answer the question below:

The

filmmakers of the documentary "Machine" spent a year researching the

state of artificial intelligence (AI), in the hope their documentary might

provoke some serious thinking on the subject before it's too late.

"There's a lot of decisions we're making right now that will have ripple

effects for decades to come," says Justin Krook, the director of the film.

"In the whole history of humanity we've never had so much power at our

disposal, and we only have one chance to get these decisions right”. Given this,

the filmmakers contend, it is important to consider the potential consequences

and ethical implications of AI now – before it becomes more advanced. Michael

Hilliard, one of the film’s producers, admits that right now, "the machine

is not actually that smart". But that doesn't mean it's not to be feared:

as the filmmakers argue, decisions we make in 2019, 2020 will affect the world

in 2050 and 2060.

Question 1b

Read the following passage from a newspaper report and then answer the question below:

When

the COVID-19 pandemic arrived in Australia in the early days of 2020, employees

and employers scrambled to implement work-from-home policies. As restrictions

eased across Australia in 2022, employers found themselves in a tug of war with

employees who were keen to retain their new-found pandemic privileges. Amantha

Imber, founder of behavioural science consultancy Inventium, says that employers

need to continue offering flexible work arrangements in order to attract and

retain talent. The evidence is hard to argue with: in November 2022, the most

searched term on SEEK was "working from home", and businesses are seeing

an ever-growing number of requests to keep pandemic policies, such as flexible

working, in the new year.
