69. Quantum superposition is a fundamental 71. Ambulance drones are uncrewed vehicles
concept in quantum mechanics. It suggests
that particles can exist in multiple states at
once until they are observed. ---- In this
experiment, a hypothetical cat is sealed in a
box, and it is considered both alive and dead
simultaneously until the box is opened and the
cat’s state is observed. It shows the strange
nature of quantum mechanics, where particles
can display behaviours that contradict
classical reasoning.
A) Schrödinger’s cat has become a popular
metaphor in discussions about the nature of
reality.
B) Schrödinger used a radioactive atom, a Geiger
counter, a hammer, and a vial of poison.
C) Scientists use the concept and refer to the
experiment to emphasise the importance of
observation.
D) Being in multiple states is against our
understanding of everyday reality and
classical physics.
E) Schrödinger’s cat is a thought experiment that
is used to illustrate this concept.
70. Some fish species have been discovered to
use sound to communicate, just like marine
mammals or many land species. ---- While
the Atlantic croakers produce sounds to
convey information about their size, strength,
and reproductive status, some fish, like the
damselfish, use sound to keep other animals
away and protect their nests. For the scientific
world, these vocalisations are very important
in terms of recognising both fish and their
freshwater ecosystems.
A) However, these acoustic signals do not serve
the same purpose for every fish species.
B) The toadfish make sounds by moving an
organ called the swim bladder in their bodies.
C) Researchers use recorders in order to gather
many kinds of data from marine ecosystems.
D) As fish lack the ability to create sounds like
mammals, they utilise distinct methods.
E) Yet, some noises, such as those made during
feeding, are produced unintentionally.
designed to get medical supplies to
emergency sites quickly. ---- Their small size
also allows them to access hard-to-reach
areas immediately. Thus, these drones can
significantly reduce response times in critical
situations, which could potentially save lives.
With real-time monitoring technology built in,
ambulance drones ensure efficient and timely
delivery of medical assistance, enhancing
emergency healthcare services.
A) Traditional ambulances with human emergency
responders may still be more effective.
B) Thanks to high-tech navigation systems, they
can get around urban areas with precision.
C) They have limited payload capacity, which may
not be able to carry large medical equipment.
D) Their use can ease burdens on emergency
services by providing faster medical attention.
E) Some technical issues could seriously delay or
hinder the delivery of vital supplies.
72. The exposome is a concept that encompasses
all the environmental exposures a person gets
throughout their life. These exposures include
everything from the air we breathe and the
food we eat to the chemicals we encounter and
the stress we experience. ---- By studying the
exposome, scientists hope to identify external
factors that contribute to diseases. All in all, this
approach shifts the focus from just our genetic
makeup to the broader picture of our environment
and lifestyle.
A) Exposome research poses several challenges
for researchers in terms of its complexity.
B) The idea is to understand how all of these
interact with our genes and influence our
health.
C) Another belief suggests that an individual’s
health is mainly determined by their genetics.
D) Air pollution affects billions worldwide and
poses significant risks to respiratory health.
E) Traditional methods for measuring these
factors are costly and time-consuming.
