Task: Question Answering
Input (English): Passage: In 2013, the northern atolls of the Marshall Islands experienced drought. The drought left 6,000 people surviving on less than 1 litre (0.22 imp gal; 0.26 US gal) of water per day. This resulted in the failure of food crops and the spread of diseases such as diarrhea, pink eye, and influenza. These emergencies resulted in the United States President declaring an emergency in the islands. This declaration activated support from US government agencies under the Republic's "free association" status with the United States, which provides humanitarian and other vital support. Question: What official declared a state of emergency in the Marshall Islands in response to the drought?
Output (English): the United States President
