Some industry commentators argue that the recent surge in malicious mobile apps found on independent app marketplaces is the result of new restrictions imposed by the major app-store platforms. Yet none of the developers removed from the major platforms, the commentators’ alleged culprits, has released a new app on those alternative marketplaces.
Which of the following, if true, most seriously weakens the argument made in the editorial?
(A) Many of the malicious apps found on independent marketplaces resemble legitimate apps removed from major platforms and are offered by unrelated developers.
(B) Historically, the independent marketplaces have had far fewer resources to detect and remove malicious apps than major app-store platforms do.
(C) Shortly after the policy changes were announced, several new developer groups began targeting independent marketplaces to distribute apps with fewer compliance checks.
(D) The major app-store platforms did not coordinate their policy changes with one another.
(E) Some users continue to prefer downloading apps through official app stores, even after the policy changes.
This is a tough question for me. Question stem asks us to weaken argument made in the editorial.
But is editorial referring to the whole passage hence a viewpoint of author, or the argument made by commentators?
Nevertheless, I still have to weaken the fact that:
new restriction imposed on major app platform --> surge in malicious apps in independent app platform
We also know that commentators think this is done by developer from major app platform who got removed but in reality it is not them
(A) Many of the malicious apps found on independent marketplaces resemble legitimate apps removed from major platforms and are offered by unrelated developers.
=Might explain alternate cause. KEEP
(B) Historically, the independent marketplaces have had far fewer resources to detect and remove malicious apps than major app-store platforms do.
=If independent app platform had poor resources to detect malicious apps, this might explain alternate cause why there is a surge in malicious apps. But this is 'historically'. We don't know how it is now after the new restriction imposed. Eliminated
(C) Shortly after the policy changes were announced, several new developer groups began targeting independent marketplaces to distribute apps with fewer compliance checks.
=Strengthen in author's viewpoint. However, this choice talks about new developer which weaken the commentators' beleive that this is done by removed app developer from major platform. Let's KEEP
(D) The major app-store platforms did not coordinate their policy changes with one another.
Irrelevant
(E) Some users continue to prefer downloading apps through official app stores, even after the policy changes.
Irrelevant
Between A and C.
If we are talking about weakening commentator's argument that surge in malicious apps is from new restriction imposed and from developer who are removed from major app platform, both A and C weaken in a way that it is not from major apps developer but someone else. However, choice A also provide alternate explanation that the surge is not from new restriction by saying that the apps found there already resemble the apps that were removed which are developed by unrelated developer, so maybe they are developing these apps with no knowledge about the new imposed restrictions.
If we are weakening the author, then it's clear that choice A is correct because choice C actually strengthens.
Answer = A
