A feral cat is a domestic cat that was raised in the wild, without having experienced  significant human contact. Feral cats differ from stray cats, in that strays were  previously pets which became nomadic. Unlike strays, feral cats initially show  hostility towards humans, particularly upon first contact. Feral cats may become  invasive to ecosystems, particularly on insular islands, resulting in a decline in  biodiversity. Non-indigenous feral cats often have few natural predators, and prey  on local species unaccustomed to defending against cats. Ground nesting birds,  small native mammals and even amphibian species are often impacted by invasive  populations of feral cats, and have led to extinctions of these species in some  cases.

Q1: Both stray and feral cats exhibit hostility when first encountering humans.

Q2: Biodiversity can be affected by feral cat populations.

Q3: Feral cats are rarely preyed upon.

The paradox of thrift, as popularised by John Keynes, highlights the fact that  excessive saving during times of economic recession negatively impacts the  economy. When spending is reduced due to excessive saving, aggregate demand  falls, resulting in lowered economic growth. This excessive saving results in reduced  economic growth, which in turn encourages further excessive saving, causing a  vicious cycle. Reduced economic growth results in reductions in salary, job security  and interest on savings, negatively impacting both savers and the economy.

However, it could be argued that savings held in savings accounts represent loanable  capital, which banks could use to stimulate the economy via lending and investment.

Q4: Excessive saving has no impact on economic growth.

Q5: Excessive saving has no impact on savers themselves.

The Moravec’s paradox is the counter intuitive discovery by artificial intelligence  researchers that advanced reasoning requires very little computational power, but  basic sensory-motor skills are incredibly computationally complex. Activities considered  complex by human standards, such as calculating statistics and playing chess are very  easily accomplished by artificial intelligences. However, extremely basic activities, such  as recognising faces or walking up a set of stairs requires vast computational  resources, and can only be accomplished by the most advanced artificial intelligences.  Although futurists predict a supersession of human workers by artificial intelligences,  Moravec’s paradox implies that advanced professions will be usurped first, not the  simple or routine occupations, as commonly featured in science fiction.

Q6: Artificial intelligences perform advanced reasoning more effectively than  humans.

Q7: Playing chess is a complex activity among humans.

Monotremes are the only living mammals that lay eggs, rather than give birth to  live offspring. Despite their egg-laying reproductive strategy, like other mammals,  monotremes are warm blooded, produce milk and have hair on their bodies. The  most famous species of monotreme is the platypus, a duck billed, beaver tailed,  and otter footed native of eastern Australia. The platypus perplexed zoologists  upon their discovery, and even to this day, the evolution of the platypus is not well  understood. The other 4 surviving monotreme species, the echidnas, bear almost  no similarity to the platypus, and more strongly resemble other mammals. It  remains a mystery why monotremes retained the ability to lay eggs, while other  mammals are placental or marsupial.

Q8: Monotremes are the only mammals ever to have laid eggs.

Q9: The platypus appears similar to a beaver in appearance.

Q10: Platypus have hair on their bodies.



Q1: How many Bernd cars were sold in May?

Q2: What were the total sales of Tymko cars for May, June and July combined?

Q3: If the number of Bernd cars sold in July had been equal to the number of  Bernd cars sold in June, how many more Bernd cars would have been sold  during July?

Q7: Which of the countries shown experienced the largest percentage increase in  public transport spending from 2007 to 2008?

Q8: Which of the countries shown had the highest public transport spend per  capita in 2008?

Q9: In 2007 Italy had a target to spend 8% more on public transport than they did  in 2006. By how much were they short of this target?
