question:
Havana, Cuba (CNN) Hurricane Irma, which devastated much of the Caribbean in September, has claimed a new victim: Raul Castro's succession plans. On Thursday, Cuban officials said the island was still dealing with the aftermath of the killer storm and needed to postpone long-held plans for Castro, 86, to retire on February 24, 2018, when his second five-year term ends. It was to have been the first time that Cuba was ruled by a leader not named Castro since the 1959 revolution that swept Raul Castro's older brother Fidel Castro to power. The wrath of Irma, however, delayed the Communist-run island's single party elections process, which appoints the Cuban National Assembly that in turn selects Cuba's president.Cuba, dealing with Hurricane Irma aftermath, says Castro will retire in April instead of FebruaryCastro has indicated first Vice President Miguel-Diaz Canel has his blessing to be the next president 
 Question:"My second and last term will have concluded," _ told Cuban lawmakers on Thursday, "and Cuba will have a new president."
answer:
Raul Castro


question:
(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.
answer:
BPA
