SCENARIO
Please use the following to answer the next question:
Louis, a long-time customer of Bedrock Insurance, was involved in a minor car accident a few months ago.
Although no one was hurt, Louis has been plagued by texts and calls from a company called Accidentable offering to help him recover compensation for personal injury. Louis has heard about insurance companies selling customers' data to third parties, and he's convinced that Accidentable must have gotten his information from Bedrock Insurance.
Louis has also been receiving an increased amount of marketing information from Bedrock, trying to sell him their full range of their insurance policies.
Perturbed by this, Louis has started looking at price comparison sites on the internet and has been shocked to find that other insurers offer much cheaper rates than Bedrock, even though he has been a loyal customer for many years. When his Bedrock policy comes up for renewal, he decides to switch to Zantrum Insurance.
In order to activate his new insurance policy, Louis needs to supply Zantrum with information about his No Claims bonus, his vehicle and his driving history. After researching his rights under the GDPR, he writes to ask Bedrock to transfer his information directly to Zantrum. He also takes this opportunity to ask Bedrock to stop using his personal data for marketing purposes.
Bedrock supplies Louis with a PDF and XML (Extensible Markup Language) versions of his No Claims Certificate, but tells Louis it cannot transfer his data directly to Zantrum as this is not technically feasible.
Bedrock also explains that Louis's contract included a provision whereby Louis agreed that his data could be used for marketing purposes; according to Bedrock, it is too late for Louis to change his mind about this. It angers Louis when he recalls the wording of the contract, which was filled with legal jargon and very confusing.
In the meantime, Louis is still receiving unwanted calls from Accidentable Insurance. He writes to Accidentable to ask for the name of the organization that supplied his details to them. He warns Accidentable that he plans to complain to the data protection authority, because he thinks their company has been using his data unlawfully. His letter states that he does not want his data being used by them in any way.
Accidentable's response letter confirms Louis's suspicions. Accidentable is Bedrock Insurance's wholly owned subsidiary, and they received information about Louis's accident from Bedrock shortly after Louis submitted his accident claim. Accidentable assures Louis that there has been no breach of the GDPR, as Louis's contract included, a provision in which he agreed to share his information with Bedrock's affiliates for business purposes.
Louis is disgusted by the way in which he has been treated by Bedrock, and writes to them insisting that all his information be erased from their computer system.
Which statement accurately summarizes Bedrock's obligation in regard to Louis's data portability request?

SCENARIO
Please use the following to answer the next question:
T-Craze, a German-headquartered specialty t-shirt company, was successfully selling to large German metropolitan cities. However, after a recent merger with another German-based company that was selling to a broader European market, T-Craze revamped its marketing efforts to sell to a wider audience. These efforts included a complete redesign of its logo to reflect the recent merger, and improvements to its website meant to capture more information about visitors through the use of cookies.
T-Craze also opened various office locations throughout Europe to help expand its business. While Germany continued to host T-Craze's headquarters and main product-design office, its French affiliate became responsible for all marketing and sales activities. The French affiliate recently procured the services of Right Target, a renowned marketing firm based in the Philippines, to run its latest marketing campaign. After thorough research, Right Target determined that T-Craze is most successful with customers between the ages of 18 and 22. Thus, its first campaign targeted university students in several European capitals, which yielded nearly 40% new customers for T-Craze in one quarter. Right Target also ran subsequent campaigns for T- Craze, though with much less success.
The last two campaigns included a wider demographic group and resulted in countless unsubscribe requests, including a large number in Spain. In fact, the Spanish data protection authority received a complaint from Sofia, a mid-career investment banker. Sofia was upset after receiving a marketing communication even after unsubscribing from such communications from the Right Target on behalf of T-Craze.
Why does the Spanish supervisory authority notify the French supervisory authority when it opens an investigation into T-Craze based on Sofia's complaint?
