To evaluate the argument, we need to identify the underlying assumption it makes. The argument postulates that the disclosure of data collection practices will lead to users switching to software that collects less personal data, but this only makes sense if users are currently unaware of the extent of data collection. Without this assumption, the disclosure wouldn't lead to a change in user behavior.
(A) Companies that do not collect personal data will not gain any significant market share from those that do.
Probably false. Non-data-collecting companies can perfectly gain significant market share.
INCORRECT(B) Some users do not currently understand the extent of data collection involved in the software they use.
This is the key assumption in the argument. If users already knew how much data their current software collects, the disclosure wouldn't change their behavior. The argument assumes that users are not fully aware of the data collection practices and that once this information is disclosed, they may be more likely to switch to software that collects less personal data.
CORRECT(C) The main reason for not adopting the proposed regulation cited above is to protect major software companies from losing market share.
The argument does not discuss why the regulation might not be adopted. Instead, it focuses on the consequences of the regulation being enacted. The assumption is not about the reasons for not adopting the regulation, but about the impact of disclosure.
INCORRECT(D) Only major software companies collect significant amounts of personal data from their users.
This is not assumed in the argument. While major companies may be more likely to collect significant amounts of data, the argument does not depend on this being the case. The focus is on the impact of the regulation and whether users will shift their behavior, not on the specific companies involved.
INCORRECT(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.
The argument assumes that the regulation will lead to the disclosure of data collection practices but does not specify the form the regulation should take, such as whether it requires explicit consent for each type of data.
