On 17 November 1989, The Sun headlined a page 2 news story titled "STRAIGHT SEX CANNOT GIVE YOU AIDS – OFFICIAL." The Sun favourably cited the opinions of Lord Kilbracken, a member of the All Parliamentary Group on AIDS. Lord Kilbracken said that only one person out of the 2,372 individuals with HIV/AIDS mentioned in a specific Department of Health report was not a member of a "high risk group", such as homosexuals and recreational drug users. The Sun also ran an editorial further arguing that "At last the truth can be told... the risk of catching AIDS if you are heterosexual is "statistically invisible". In other words, impossible. So now we know – everything else is homosexual propaganda." Although many other British press services covered Lord Kilbracken's public comments, none of them made the argument that the Sun did in its editorial and none of them presented Lord Kilbracken's ideas without context or criticism.
Whose opinion did The Sun trust in their AIDS reporting?
A: Lord Kilbracken

Due to the 1973 spike in oil prices, the economy of Iran was flooded with foreign currency, which caused inflation. By 1974, the economy of Iran was experiencing double digit inflation, and despite many large projects to modernize the country, corruption was rampant and caused large amounts of waste. By 1975 and 1976, an economic recession led to increased unemployment, especially among millions of youth who had migrated to the cities of Iran looking for construction jobs during the boom years of the early 1970s. By the late 1970s, many of these people opposed the Shah's regime and began to organize and join the protests against it.
Why did millions of youth migrate to the urban areas of Iran in the mid 1970s?
A: construction jobs

Maternal factors also play a role in the body’s immune response. At birth, most of the immunoglobulin present is maternal IgG. Because IgM, IgD, IgE and IgA don’t cross the placenta, they are almost undetectable at birth. Some IgA is provided by breast milk. These passively-acquired antibodies can protect the newborn for up to 18 months, but their response is usually short-lived and of low affinity. These antibodies can also produce a negative response. If a child is exposed to the antibody for a particular antigen before being exposed to the antigen itself then the child will produce a dampened response. Passively acquired maternal antibodies can suppress the antibody response to active immunization. Similarly the response of T-cells to vaccination differs in children compared to adults, and vaccines that induce Th1 responses in adults do not readily elicit these same responses in neonates. Between six to nine months after birth, a child’s immune system begins to respond more strongly to glycoproteins, but there is usually no marked improvement in their response to polysaccharides until they are at least one year old. This can be the reason for distinct time frames found in vaccination schedules.
For how long do these antibodies have an effect on infants?
A: up to 18 months

To create green sparks, fireworks use barium salts, such as barium chlorate, barium nitrate crystals, or barium chloride, also used for green fireplace logs. Copper salts typically burn blue, but cupric chloride (also known as "campfire blue") can also produce green flames. Green pyrotechnic flares can use a mix ratio 75:25 of boron and potassium nitrate. Smoke can be turned green by a mixture: solvent yellow 33, solvent green 3, lactose, magnesium carbonate plus sodium carbonate added to potassium chlorate.
What else are copper salts used for?
A:
