question:
UNITED NATIONS (Reuters) - The United States will seek to boost its case for United Nations action against Iran when Security Council envoys visit Washington on Monday to view pieces of weapons that  U.S. Ambassador Nikki Haley  says Tehran gave to Yemenâs Houthi group.
 Haley  and  her  14 council colleagues will also lunch with President Donald Trump  the U.S. Mission to the United Nations said Friday.
The U.N. ambassadors will visit a military hangar at Joint Base Anacostia-Bolling near Washington  where  Haley   the U.S envoy to the United Nations  last month presented remnants of what the Pentagon said was an Iranian-made ballistic missile fired from Yemen on Nov. 4 at Saudi Arabiaâs capital Riyadh  as well as other weapons.
 Haley  said last month  she  was exploring several U.N. options for pressuring Iran to âadjust their behaviorâ. But  she  is likely to struggle to convince some Security Council members  like veto powers Russia and China  that U.N. action is needed.
 Haley  has said the Security Council could strengthen the provisions in that resolution or adopt a new resolution banning Iran from all activities related to ballistic missiles. To pass  a resolution needs nine votes in favor  and no vetoes by the United States  Britain  France  China or Russia.
Diplomats  speaking on condition of anonymity  say  Haley  has not signaled which accountability option  she  might pursue or when.
answer:
U.S. seeks to boost case against Iran with U.N. Washington visit


question:
Gates said the performance of both Pakistan's military and civilian government over the past 16 months had exceeded Washington's expectations  in an interview with Al-Jazeera  the Qatar-based satellite news channel.
"I think if you look back  15 or 16 months  the Pakistani government has performed admirably " Gates said  according to a transcript.
Gates cited Pakistan's "success" in the Swat Valley  where two million people fled a punishing military offensive against Taliban insurgents beginning in late April.
Gates added that he was pleased with the security of Pakistan's nuclear arsenal  calling the arrangements in place "sufficient and adequate."
"I'm quite comfortable that the security arrangements for the Pakistani nuclear capabilities are sufficient and adequate " he said.
He said that assessment was "based both on our own understanding of the security arrangements that the Pakistanis have for their weapons and their capabilities  their laboratories and so on. But also the insurances we have been given by the Pakistanis."

question:
The study's lead author  Zachary Ward   described the forecast as "sobering."
But   he  added  "It should not be surprising that we are heading in this direction. We are already approaching this level of adult obesity for certain subgroups [and] areas of the country."
Still   Ward  expressed some surprise at how strongly being obese at a very young age predicted obesity decades down the road.
 Ward  is a doctoral candidate in health policy with the Harvard T.H. Chan School of Public Health's Center for Health Decision Science  in Boston.
The study by  Ward  and  his  colleagues appears in the Nov. 30 issue of the New England Journal of Medicine.
