IMO BTo determine which assumption the argument relies on, let's break down the argument:
Proposed regulation: Requires software companies to disclose all data collection practices upfront.
Expected outcome: Users may switch to software that collects less personal data.
Consequence: Some companies may lose significant market share.
The argument assumes that users currently lack full knowledge of data collection practices and that this lack of knowledge influences their choice of software. If users were fully aware of the extent of data collection, they might choose different software, leading to a shift in market share.
Let's analyze each option to see which one the argument depends on:
(A) Companies that do not collect personal data will not gain any significant market share from those that do.
This contradicts the argument. The argument suggests that companies that collect less personal data will gain market share.
(B) Some users do not currently understand the extent of data collection involved in the software they use.
This supports the argument. If users do not understand the extent of data collection, disclosing these practices could lead them to switch to software that collects less personal data.
(C) The main reason for not adopting the proposed regulation cited above is to protect major software companies from losing market share.
This is not directly related to the argument. The argument is about the effect of the regulation, not the reasons for or against its adoption.
(D) Only major software companies collect significant amounts of personal data from their users.
This is not necessary for the argument. The argument can hold even if smaller companies also collect significant data.
(E) Disclosure laws should be designed such that software companies are allowed to collect data only if users have explicitly consented to each type of data being collected.
This is a suggestion for how disclosure laws should be designed, not an assumption the argument relies on.
The argument relies on the assumption that users currently do not fully understand the extent of data collection. If they did, they might choose different software, leading to a shift in market share. Therefore, the correct answer is:
(B) Some users do not currently understand the extent of data collection involved in the software they use.
