Problem: In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a name used by the APG IV system for a clade within the monocots, which in its turn is a clade within the angiosperms. The commelinids are the only clade that the APG has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch, the other two groups being the alismatid monocots and the lilioid monocots.

Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid.

The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of the monocots. However, by the release of his 1980 system of classification, he had merged this subclass into a larger one no longer considered to be a clade.

The commelinids constitute a well-supported clade within the monocots, and this clade has been recognized in all four APG classification systems.

The commelinids of APG II (2003) and APG III (2009) contain essentially the same plants as the commelinoids of the earlier APG system (1998). In APG IV (2016) the family Dasypogonaceae is no longer directly placed under commelinids but instead a family of order Arecales.

Problem: Digital rights management (DRM) is a set of access control technologies for restricting the use of proprietary hardware and copyrighted works. DRM technologies try to control the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems within devices that enforce these policies.

The use of digital rights management is not universally accepted. Proponents of DRM argue that it is necessary to prevent intellectual property from being copied freely, just as physical locks are needed to prevent personal property from being stolen, that it can help the copyright holder maintain artistic control, and that it can ensure continued revenue streams. Those opposed to DRM contend there is no evidence that DRM helps prevent copyright infringement, arguing instead that it serves only to inconvenience legitimate customers, and that DRM helps big business stifle innovation and competition. Furthermore, works can become permanently inaccessible if the DRM scheme changes or if the service is discontinued. DRM can also restrict users from exercising their legal rights under the copyright law, such as backing up copies of CDs or DVDs (instead having to buy another copy, if it can still be purchased), lending materials out through a library, accessing works in the public domain, or using copyrighted materials for research and education under the fair use doctrine, and under French law. The Electronic Frontier Foundation (EFF) and the Free Software Foundation (FSF) consider the use of DRM systems to be an anti-competitive practice.

Problem: CHAPTER XXX

THE ENEMY RUNS AWAY

In a very few minutes Dave and his chums were on the way to find Merwell and Jasniff. As the party walked along Hooker Montgomery told more about his dealings with the rascally students. It was plain to Dave that the so-styled doctor had been nothing but a weak tool, and in a way the youth had to pity the poor wretch whom dissipation had so dragged down.

In less than five minutes the party arrived at a small residence set well back in a garden. The walk was unshoveled, and they had to pick their way through the snow. When they rang the doorbell a tall, thin elderly woman answered their summons.

"Good-evening, Mrs. Slater," said Hooker Montgomery. "I'd like to see Mr. Merwell and Mr. Jasniff."

"They have gone," was the sharp answer, and Mrs. Slater looked as if she wished to shut the door in the faces of the callers.

"When will they be back?"

"They won't be back."

"Will you kindly tell me where they have gone?" questioned Dave.

"Who are you?" And the woman eyed Dave suspiciously.

"My name is David Porter, and I wish to see Merwell and Jasniff very much."

"Porter! Then you must be that young villain Link told me about--the one who made so much trouble for him out on the ranch!" exclaimed Mrs. Slater. "Well, you can't see Link, or his friend. They have gone, and they won't be back."

"Have they gone to Rockville Academy?"
