We're not sure.
If you don't know, brewer's yeast is an active yeast used in the production of beer. It's a rich source of minerals, particularly chromium, protein and B-complex vitamins, including thiamin. It tastes bitter if ingested alone.
Jump back to the thiamin. Those with diets high in B-complex vitamins report fewer insect bites.
The vitamin emits an odor unattractive to insects during perspiration, but undetectable to humans. Good sources of thiamin include whole grains, organ meats and - surprise, surprise - brewer's yeast.
You can find brewer's yeast in tablet form, and these products promise mosquito relief for more than 24 hours.
However, several scientific studies refute the claims of brewer's yeast and its repellent powers.
Type "Does brewer's yeast prevent mosquito bites?" in an Internet search engine and you'll find an equal split of sites affirming and denying brewer's yeast alleged ability to prevent mosquito bites.
So make up your own mind.
How much gasoline do you get from a gallon of crude oil and how many gallons of crude oil are in a barrel?
According to various online sources, there are 42 gallons in a barrel of crude oil. The refining process yields about 20 gallons of gasoline and other crude-based products.
When did stop signs change from yellow to red?
Yellow stop signs? What are you talking about?
The Bureau of Public Roads, now the Federal Highway Administration, amended the 1948 Manual on Uniform Traffic Control Devices for Streets and Highways in 1954.
The amendment decreed all stop signs must be red with a white legend and border.
Stop signs featured a black legend and border from 1923 to 1954. Yellow provided greater visibility, and was believed to be more durable.
This changed in the early 1950s, when red reflectorized sheeting and its visibility and durability proved a worthy successor to yellow paint.
The 1923 committee that decided on yellow and black met in Detroit, recipient of the first recorded stop sign in 1915. Before that, cities used semaphores, traffic towers and hand-held signs to get cars to stop.
The 1923 committee also decided on the sign's distinctive octagon shape.
Early stop signs were placed at intersections where the minor street should stop for a major street.
Eclectic efforts to glam-up the stop sign and make it more visible included using cat's eyes - reflective glass semicircles set in holes in the metal which spelled "STOP."
And in the 1940s, it was popular to sprinkle glass beads on wet paint.
Why was it forbidden to sell sliced bread in the U.S. during World War II?
We thought this a phony question, and researched it for kicks online. The joke's on us, I guess.
Most of you probably don't know that on Jan. 18, 1943, the Secretary of Agriculture banned the sale of sliced bread in the United States until the end of the war.
And why?
The metal from bread-slicing machines was needed for weapons, ammunition, tanks and other war supplies.
You can spend the better part of a lifetime in school and still not know diddly or squat, and this answer is partial proof.
Many of you already think the GYA staff doesn't know diddly or squat.
