Input: Read this: The latest study using magnetic resonance imaging (MRI) to humans and dogs together proved that dogs have same response to voices and use the same parts of the brain as humans to do so. This gives dogs the ability to recognize emotional human sounds, making them friendly social pets to humans.
Question: An MRI study on dogs proved that dogs have the same response as humans to what?

Output: voices

Input: Read this: The United States and the Soviet Union were the first two countries to recognize the State of Israel, having declared recognition roughly simultaneously. The United States regards Israel as its "most reliable partner in the Middle East," based on "common democratic values, religious affinities, and security interests". Their bilateral relations are multidimensional and the United States is the principal proponent of the Arab-Israeli peace process. The United States and Israeli views differ on some issues, such as the Golan Heights, Jerusalem, and settlements. The United States has provided $68 billion in military assistance and $32 billion in grants to Israel since 1967, under the Foreign Assistance Act (period beginning 1962), more than any other country for that period until 2003.
Question: Who were the first two countries to recognize the State of Israel?

Output: United States and the Soviet Union

Input: Read this: The evolution of seed plants and later angiosperms appears to be the result of two distinct rounds of whole genome duplication events. These occurred at 319 million years ago and 192 million years ago. Another possible whole genome duplication event at 160 million years ago perhaps created the ancestral line that led to all modern flowering plants. That event was studied by sequencing the genome of an ancient flowering plant, Amborella trichopoda, and directly addresses Darwin's "abominable mystery."
Question: What type of event perhaps created the line which led to modern flowering plants?

Output: whole genome duplication

Input: Read this: Nakamura was awarded the 2006 Millennium Technology Prize for his invention. Nakamura, Hiroshi Amano and Isamu Akasaki were awarded the Nobel Prize in Physics in 2014 for the invention of the blue LED. In 2015, a US court ruled that three companies (i.e. the litigants who had not previously settled out of court) that had licensed Mr. Nakamura's patents for production in the United States had infringed Dr. Moustakas's prior patent, and order them to pay licensing fees of not less than 13 million USD.
Question: How many companies did a judge say infringed on Dr. Moustakas's prior blue light patent in 2015?

Output:
three
