Input: 

Mexico's new president, Felipe Calderon, seems to be doing all the right things in cracking down on Mexico's drug traffickers. He's appointed new people to key military and criminal justice positions, deployed troops to quell drug violence, reasserted federal police power, extradited a few major traffickers to the United States, and given a green light to legislation clarifying Mexico's drug laws. But all this provides little reason to hope that Mexico has really turned a corner in its efforts to control the illegal drug trade. For a guide to what's in store, one need only look at past sexenios (the six year terms of Mexican presidents).

Sentence: Mexico has drug traffickers.

Output: Yes

Wilder and his colleagues are cautious about their results also because the data do not make clear whether it was the anesthesia that contributed to the children's learning deficits, or whether it was an underlying condition that may have required surgery and precipitated the learning problems. Of the more than 5,000 babies studied, 593 needed at least one surgery and just over 100 infants needed more than two before age 3. There may be something unusual about this population of children that could have made them vulnerable to learning problems and required they undergo surgery and anesthesia.

Sentence: It has been posited that anesthesia may be responsible for the learning disabilities of certain children.

Output:
Yes
