Q: proper question: What group has no feeding appendages?
disfluent question: What does or rather what group has no feeding appendages?
context: The Beroida, also known as Nuda, have no feeding appendages, but their large pharynx, just inside the large mouth and filling most of the saclike body, bears macrocilia at the oral end. These fused bundles of several thousand large cilia are able to bite off pieces of prey that are too large to swallow whole almost always other ctenophores. In front of the field of macrocilia, on the mouth lips in some species of Beroe, is a pair of narrow strips of adhesive epithelial cells on the stomach wall that zip the mouth shut when the animal is not feeding, by forming intercellular connections with the opposite adhesive strip. This tight closure streamlines the front of the animal when it is pursuing prey.

A: The Beroida

Q: proper question: What type of skills does the market bid down compensation for?
disfluent question: What forces er what type of skills does the market bid down compensation for?
context: Economist Joseph Stiglitz argues that rather than explaining concentrations of wealth and income, market forces should serve as a brake on such concentration, which may better be explained by the non-market force known as rent-seeking. While the market will bid up compensation for rare and desired skills to reward wealth creation, greater productivity, etc., it will also prevent successful entrepreneurs from earning excess profits by fostering competition to cut prices, profits and large compensation. A better explainer of growing inequality, according to Stiglitz, is the use of political power generated by wealth by certain groups to shape government policies financially beneficial to them. This process, known to economists as rent-seeking, brings income not from creation of wealth but from grabbing a larger share of the wealth that would otherwise have been produced without their effort

A:
None
