Example Input: (CNN) Your "BPA-free" plastic product may be no safer than the product it replaced, says a new UCLA study that analyzed the impact of a common BPA alternative on zebra fish embryos. The study joins a small but growing group of similar research sounding the alarm about so called "BPA-free" alternatives. "Our findings are frightening and important," said senior author and reproductive endocrinologist Nancy Wayne. "Consider it the aquatic version of the canary in the coal mine." After decades of animal research linked BPA (Bisphenol A), a known endocrine disruptor, to problems with brain and reproductive development, early puberty and a rise in breast and prostate cancer, many manufacturers stopped using the chemical to harden plastics, replacing it with "BPA-free" alternatives. The most common replacement is BPS (Bisphenol S), said Wayne.BPA-free alternatives may be no safer than BPA, say researchersMost common alternative, BPS, linked in study to disruptions of estrogen and thyroid hormones 
 Question:In addition to the effect on estrogen, the study also found both _ and BPS affected the thyroid hormone system.
Example Output: BPA

Around his neck, the Islamic State butchers who killed him had hung a handwritten placard accusing him of apostasy — abandoning his religion. He was just 17 and the placard explained that the unnamed boy's crime had been to take photographs of the terrorist organisation's headquarters in the Syrian city of Raqqa, which has become the de facto IS capital. Images of his body were smuggled to the West in defiance of the city's terrifying religious police by undercover activists appalled at the daily brutality taking place in their city.Women are forced to become sex slaves, shared by the brutal jihadisLife in Raqqa once revolved around cotton farming.
