A study published in the Neuropsychopharmacology journal in 2013 revealed the finding that the flavour of beer alone could provoke dopamine activity in the brain of the male participants, who wanted to drink more as a result. The 49 men in the study were subject to positron emission tomography scans, while a computer-controlled device sprayed minute amounts of beer, water and a sports drink onto their tongues. Compared with the taste of the sports drink, the taste of beer significantly increased the participants desire to drink. Test results indicated that the flavour of the beer triggered a dopamine release, even though alcohol content in the spray was insufficient for the purpose of becoming intoxicated.
What hormone can be triggered by the flavor of beer alone in males?
****
The answer: dopamine


The problem: Answer a question about this article:
The USB standard specifies relatively loose tolerances for compliant USB connectors to minimize physical incompatibilities in connectors from different vendors. To address a weakness present in some other connector standards, the USB specification also defines limits to the size of a connecting device in the area around its plug. This was done to prevent a device from blocking adjacent ports due to the size of the cable strain relief mechanism (usually molding integral with the cable outer insulation) at the connector. Compliant devices must either fit within the size restrictions or support a compliant extension cable that does.
Due to size restrictions compliant devices must what?
****
The answer: fit within the size restrictions or support a compliant extension cable that does

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.
In what section of London can mobile shellfish stalls still be found today?
****
The answer: East End
