13. 1778 - half the Banda Islands’ nutmeg plantations were destroyed by a ______
Key words: 1778, half, Banda Islands, destroyed
An event in 1778 is mentioned in paragraph 6: “a volcanic eruption in the Banda region
caused a tsunami that wiped out half the nutmeg groves”. “Wipe out” has the same
meaning as “destroy”, and it can be understood that the tsunami was the direct cause of
this event. Therefore, tsunami is the missing word here.
destroy = wipe out
→ Answer: tsunami

Test 1 – Passage 2 – Cambridge 15
Driverless cars
A The automotive sector is well used to adapting to automation in manufacturing. The
implementation of robotic car manufacture from the 1970s onwards led to
significant cost savings and improvements in the reliability and flexibility of vehicle
mass production. A new challenge to vehicle production is now on the horizon and,
again, it comes from automation. However, this time it is not to do with the
manufacturing process, but with the vehicles themselves.
Research projects on vehicle automation are not new. Vehicles with limited self
driving capabilities have been around for more than 50 years, resulting in significant
contributions towards driver assistance systems. But since Google announced in
2010 that it had been trialling self-driving cars on the streets of California, progress
in this field has quickly gathered pace.
B There are many reasons why technology is advancing so fast. One frequently cited
motive is safety; indeed, research at the UK's Transport Research Laboratory has
demonstrated that more than 90 percent of road collisions involve human error as a
contributory factor, and it is the primary cause in the vast majority. Automation may
help to reduce the incidence of this.
Another aim is to free the time people spend driving for other purposes. If the
vehicle can do some or all of the driving, it may be possible to be productive, to
socialise or simply to relax while automation systems have responsibility for safe
control of the vehicle. If the vehicle can do the driving, those who are challenged by
existing mobility models - such as older or disabled travellers - may be able to enjoy
significantly greater travel autonomy.
C Beyond these direct benefits, we can consider the wider implications for transport
and society, and how manufacturing processes might need to respond as a result. At
present, the average car spends more than 90 percent of its life parked. Automation
means that initiatives for car-sharing become much more viable, particularly in
urban areas with significant travel demand. If a significant proportion of the
population choose to use shared automated vehicles, mobility demand can be met by
far fewer vehicles.
D The Massachusetts Institute of Technology investigated automated mobility in
Singapore, finding that fewer than 30 percent of the vehicles currently used would
be required if fully automated car sharing could be implemented. If this is the case,
it might mean that we need to manufacture far fewer vehicles to meet demand.
However, the number of trips being taken would probably increase, partly because
empty vehicles would have to be moved from one customer to the next.

Modelling work by the University of Michigan Transportation Research Institute
suggests automated vehicles might reduce vehicle ownership by 43 percent, but that
vehicles' average annual mileage would double as a result. As a consequence, each
vehicle would be used more intensively, and might need replacing sooner. This
faster rate of turnover may mean that vehicle production will not necessarily
decrease.
E Automation may prompt other changes in vehicle manufacture. If we move to a
model where consumers are tending not to own a single vehicle but to purchase
access to a range of vehicles through a mobility provider, drivers will have the
freedom to select one that best suits their needs for a particular journey, rather than
making a compromise across all their requirements.
Since, for most of the time, most of the seats in most cars are unoccupied, this may
boost production of a smaller, more efficient range of vehicles that suit the needs of
individuals. Specialised vehicles may then be available for exceptional journeys,
such as going on a family camping trip or helping a son or daughter move to
university.
F There are a number of hurdles to overcome in delivering automated vehicles to our
roads. These include the technical difficulties in ensuring that the vehicle works
reliably in the infinite range of traffic, weather and road situations it might
encounter; the regulatory challenges in understanding how liability and enforcement
might change when drivers are no longer essential for vehicle operation; and the
societal changes that may be required for communities to trust and accept automated
vehicles as being a valuable part of the mobility landscape.
G It's clear that there are many challenges that need to be addressed but, through
robust and targeted research, these can most probably be conquered within the next
10 years. Mobility will change in such potentially significant ways and in
association with so many other technological developments, such as telepresence
and virtual reality, that it is hard to make concrete predictions about the future.
However, one thing is certain: change is coming, and the need to be flexible in
response to this will be vital for those involved in manufacturing the vehicles that
will deliver future mobility.
