Dragnet Verbal Reasoning Questions and Answers


Is free internet access as much a universal human right as access to clean water and healthcare? Many leading experts believe that the 80% of the world’s population that is not connected to the web should have access to information through free low-bandwidth connection via mobile phones. The one fifth of the world connected to the internet, however, faces a very different problem: an insatiable appetite for bandwidth that outstrips availability. Bandwidth refers to the capacity to transfer data through a channel. Emails, for example, require less bandwidth than video. Information traffic jams result when too many users try to move information at the same time, exceeding the channel’s capacity. The popularity of mobile web devices means demand for wireless channels is growing rapidly, but bandwidth supply is limited – resulting in high charges for use. With bandwidth controlled by a handful of private suppliers, bandwidth is the subject of government debate in many countries, including the United States. Bandwidth
suppliers are in favour of introducing tiered pricing structures, whereby customers paying higher rates would receive faster service. Critics believe that a tiered system violates the principle of net neutrality – whereby all data is treated as equal – and would allow suppliers to profiteer from controlling a scarce resource.
Suppliers argue that they are funding huge infrastructure updates – such as switching from copper wires to expensive fiberoptics – in order to improve services.


116)

Which two of these statements must be true?

(True) Proponents of net neutrality are against the prioritising of certain web traffic.
Very True – as explained in line 9 and 10 of the passage

(True) Even those with internet connection are still unsatisfied for new bandwidth
Very True – as seen in line 6 of the passage

(Cannot say) Free internet access is as much a universal human right
The passage never stated this as a fact, it asked this as an question – first line of the passage

(Cannot say) Traffic jams results only when information are moved at the same time
The passage never said that traffic jam ONLY results when information are moved at the same time. See line 8 and 9 of the passage
117)

Which two of these statements must be true?

(False) The bandwidth for emails and video are the same
The passage states that mails require less bandwidth than video – line 8 of the passage

(True) Switching from copper wires to expensive fiberoptics will increase bandwidth service
Very true – as seen in the last line of the passage

(True) Capacity to transfer data through a channel is bandwidth
Very true – as seen in the 6th line of the passage

(Cannot say) The tiered pricing structures would charge mobile web devices users more
While the 7th sentence states that mobile web devices are subject to high charges, the
tiered pricing structures described in the 9th sentence does not mention costs for mobile
web devices, merely a cost associated with a faster service
118)

Which two of these statements must be true?

(Cannot say) Tired system violates the principle of neutrality
The passage never stated this as a fact, it was actually critics that believe that tired system violates this principle and we cannot take the belief of critics as a fact; this is seen in the last five lines of the passage.

(False) Demand for wireless channels is limited, but bandwidth supply is growing
This is false because the passage says otherwise; line 10 and 11 of the passage states that demand for wireless is growing but bandwidth is limited

(True) Mobile net device increase has contributed towards the pressure on bandwidth availability
Very true – as stated in the 7th sentence

(True) Only a few suppliers control bandwidth supply
Very true – as seen in the 12th sentence

 
119)

Which two of these statements must be true?

(False) The main argument in the passage is that internet users are not leaving enough bandwidth for 80% of the world’s population.
The passage raises two separate problems- lack of internet connection for 80% of the World and bandwidth shortage for internet users- but there is no causal relationship between the two problems

(Cannot say) Access to information via the internet is a basic human right.
The first two sentences raises this question, but do not provide an objective answer

(True) Suppliers back their demand for higher charges claiming higher infrastructural updates
Very true; as seen in the last two lines of the passage

(True) In the new proposal customers paying higher will receive faster service
Very true; as seen in the last five lines

The most prevalent neurological condition in the developed world, migraine is characterised by severe, recurrent headaches, with additional symptoms including nausea and sensitivity to light and sound. The frequency and duration of migraine attacks are variable: attacks may occur a few times a year or several times per month, while pain may last between four hours and three days. Approximately one third of sufferers experience an aura – a perceptual disturbance occurring before the migraine’s onset. There are numerous theories on the cause of migraines.

The vascular theory posits that migraines are caused by problems with blood vessels in the brain. A more widely held view is that migraines result from low levels of the neurotransmitter serotonin in the brain. Prophylactic drug treatment, which prevents the onset of migraines, has declined in recent years, because of side effects and also improvements in medications treating an actual attack. Whereas older varieties of pain medication are potentially addictive, newer drugs called triptans work by reducing pain information travelling to the brain. Treatment plans typically include avoidance of known migraine triggers, such as diet, alcohol, and stress, as overuse of medication can lead to chronic “rebound headaches.” Not only do migraines have a debilitating effect on sufferers, they are also bad for the  economy, with an estimated 25 million days lost from work every year in the UK


120)

Which two of these statements must be true?

(Cannot say) The vascular theory has been discredited
Though the passage tells us that it is not the most widely held view, it does not necessarily follow that it has been discredited.

(True) Problems with blood vessels and serotonin deficiencies may cause migraines
Very true as seen in line 8-10 of the passage

(True) In the extensive view, migraines also affect the economy
Very true as seen in the last two lines of the passage

(Cannot say) Migraines can be cured easily
This fact was never presented in the passage, so we cannot say it is true
