Context and question: Many pubs were drinking establishments, and little emphasis was placed on the serving of food, other than sandwiches and "bar snacks", such as pork scratchings, pickled eggs, salted crisps and peanuts which helped to increase beer sales. In South East England (especially London) it was common until recent times for vendors selling cockles, whelks, mussels, and other shellfish to sell to customers during the evening and at closing time. Many mobile shellfish stalls would set up near pubs, a practice that continues in London's East End. Otherwise, pickled cockles and mussels may be offered by the pub in jars or packets.
What seafood can often be purchased in jars at pubs?
Answer: pickled cockles and mussels
Context and question: The K-12 and higher education reform programs of the Gates Foundation have been criticized by some education professionals, parents, and researchers because they have driven the conversation on education reform to such an extent that they may marginalize researchers who do not support Gates' predetermined policy preferences. Several Gates-backed policies such as small schools, charter schools, and increasing class sizes have been expensive and disruptive, but some studies indicate they have not improved educational outcomes and may have caused harm. Peer reviewed scientific studies at Stanford find that Charter Schools do not systematically improve student performance
Who has criticized charter school reform programs?
Answer:
unanswerable
