Cybersecurity Analyst: In the past, most people used secure wired connections to access the internet, which provided reliable and controlled data flow. In the last decade, Wi-Fi has become popular; it allows for greater mobility but is generally considered less secure. The concern that Wi-Fi is riskier is supported by the fact that the number of cybersecurity incidents reported was much higher last year than it was ten years ago.
Which of the following, if true, most seriously undermines the force of the evidence cited?
(A) Some individuals and businesses still use wired connections for sensitive transactions.
(B) Most people do not use advanced cybersecurity software on their devices while connected to public Wi-Fi networks.
(C) The majority of cybersecurity incidents involve the interception of data transmitted over unsecured networks.
(D) Wi-Fi technology has been adopted much more widely than wired technology, significantly increasing the number of devices connected to the internet at any given time.
(E) Wired connections are more expensive to install and maintain, leading many users to share connections and potentially expose more devices to risks.

GMAT Club's Official Explanation:
(A) Incorrect: This choice points out that some still use the older, supposedly safer method, but does not weaken the evidence and thus the argument. We can safely eliminate it.
(B) Incorrect: This is an interesting point. This does not really undermine the evidence cited and weaken the argument. Instead, it almost strengthens the argument by saying that people use insecure connections, so of course there will be more incidents. This answer choice is the opposite of what we need. Eliminate.
(C) Incorrect: This choice also supports the original argument rather than undermining it and the evidence, by telling us that unsecure connections were responsible for most incidents, again being the opposite of what we need. Eliminate.
Correct Answer (D): This answer choice introduces a factor that could explain the increase in reported cybersecurity incidents while undermining the evidence: the widespread adoption of Wi-Fi has led to a significant increase in the number of devices online, thus increasing the opportunities for cybersecurity breaches on a pure numbers basis (not percentage). Thus we could argue that the increase in incidents is not because WiFi is more insecure but because there are so many more opportunities that on a pure numbers basis, it is natural for it to increase, and the percentage of incidents as a percentage of total connections, could have actually decreased. This answer choice can undermine the evidence and the argument by suggesting that the rise in incidents could be due to the increased volume of use rather than security issues with the WiFi technology.
(E) Incorrect: This choice adds some information about the Wired connections, indicating that there are weaknesses in approach to the wired connectivity, but it does not tell us anything about incidents, only risks. Moreover, the answer choice does not specify what risks are being referred to. Had this answer choice actually told us that more people have been breached while sharing a wired connection or something along those lines, we could consider it but as is, it is vague and incomplete as is to undermine the evidence cited.

IMO D
To determine which option most seriously undermines the force of the evidence cited, we need to focus on the core claim: the increase in cybersecurity incidents is due to the increased use of Wi-Fi, which is considered less secure than wired connections.
Let's analyze each option:
(A) Some individuals and businesses still use wired connections for sensitive transactions.
This option suggests that wired connections are still in use for sensitive transactions, but it does not address the overall increase in cybersecurity incidents or provide a reason that undermines the evidence cited.
(B) Most people do not use advanced cybersecurity software on their devices while connected to public Wi-Fi networks.
This option supports the idea that Wi-Fi is less secure due to a lack of advanced cybersecurity measures, reinforcing the concern rather than undermining it.
(C) The majority of cybersecurity incidents involve the interception of data transmitted over unsecured networks.
This option supports the argument that Wi-Fi, particularly unsecured Wi-Fi, is a significant factor in cybersecurity incidents. It does not undermine the evidence cited.
(D) Wi-Fi technology has been adopted much more widely than wired technology, significantly increasing the number of devices connected to the internet at any given time.
This option suggests that the increase in cybersecurity incidents could be due to the sheer number of devices connected to the internet via Wi-Fi, rather than Wi-Fi itself being inherently less secure. This undermines the evidence by providing an alternative explanation for the increase in incidents.
(E) Wired connections are more expensive to install and maintain, leading many users to share connections and potentially expose more devices to risks.
This option suggests that wired connections also have security risks due to shared connections, but it does not directly address the increase in cybersecurity incidents related to Wi-Fi.
Between options (D) and (E), option (D) provides a more direct alternative explanation for the increase in cybersecurity incidents by attributing it to the wider adoption of Wi-Fi and the resulting increase in the number of connected devices. This explanation undermines the force of the evidence cited by suggesting that the increase in incidents is not necessarily due to Wi-Fi being less secure, but rather due to the increased number of devices and usage.
Therefore, the correct answer is:
(D) Wi-Fi technology has been adopted much more widely than wired technology, significantly increasing the number of devices connected to the internet at any given time.
