Write the right answer to the question based on the context passage.

Input: Consider Input: Jon's back ached. Frost had come early this year and the ground broke like stone. Jon had spent eight seasons breaking this ground to plant spring's crops and every year it got harder. Sweat beaded on his brow and he felt his cotton shirt stick to his skin under his coat. Jon took off his soft-brimmed hat and wiped his forehead. He examined the hat as he let his breath return.
The hat had kept the burning sun and beating rain off his head for as long as Jon owned the farm. He wore it every day. It had been a gift given to him on the day he married Alasandra but he could not remember who gave it to him. Jon put it back on his head and pushed the tiller deep into the stubborn earth.
Daven ran over the hill and down the cart path leading to their small cobblestone house. The boy had only left a short while ago and he held no sack with the bread and cheese his mother had told him to buy. Jon furrowed his brow. The boy continued to run and soon the wind carried his cry to his father's ears.
"Papa! A carriage is coming! Two horses!"
Jon's furrowed brow remained. Surely the boy meant a cart from a neighboring farm. No carriage made it out this far.
"It's from the city! A soldier drives it!"
Jon felt ice water flow over him. He turned to the house.
"Sandra! Get the musket out of the pantry!"
Jon saw his wife's face appear at one foggy window. Jon gestured wildly at her.
"Get it!"
They were too late. As Daven reached Jon, the black carriage already approached. A single figure sat on the bench, guiding the two brown horses down Jon's path. Question: Who examined their hat?

Output: Jon

Input: Consider Input: SINGAPORE In an agreement signed Tuesday in Singapore, North Korean leader Kim Jong Un "reaffirmed his firm and unwavering commitment to complete denuclearization of the Korean Peninsula," while U.S. President Donald Trump "committed to provide security guarantees" to North Korea.
The document also calls for the two countries to jointly work on efforts to build a lasting peace on the Korean Peninsula, to establish new U.S.-North Korea relations and to recover the remains of prisoners of war and military members missing in action. The two sides also promised to hold follow-up negotiations.
"We're going to denuke North Korea," Trump told VOA contributor Greta Van Susteren.
He also said neither side issued ultimatums and that the agreement Tuesday was the result of months of negotiations.
"You know that could have ended in a war, that could have ended with many millions of people you know North Korea very well, Seoul has 28 million people, that could have ended with millions of people dead but we ended with a deal," he said.
Trump also told VOA that U.S. troops stationed in South Korea will remain in place, but announced one concession long-sought by North Korea.
"We are going to get out of the war games that cost so much money," he said.
Trump said at later news conference that existing U.S. sanctions will remain in place until North Korean nuclear weapons "are no longer a factor."
As for verification, Trump said he and Kim discussed the issue and that monitoring denuclearization efforts would be achieved "by having a lot of people there." He also predicted Kim would begin work right away to "live up to" the agreement.
Asked if the talks included specifics on the size of North Korea's nuclear arsenal, Trump said "what they have is substantial."
On human rights, Trump said Tuesday's meetings only very briefly touched on the topic, but that the two sides would discuss it more in the future. When asked about thousands of people imprisoned in labor camps, Trump said he thinks he has helped them because things in North Korea will change. Question: What issue did VOA contributor Greta Van Susteren address?

Output: how long US troops will remain in place in South korea

Input: Consider Input: For the past few weeks I have been talking about the merits of the Mediterranean Diet. However, I have to acknowledge that no diet is perfect for every single person and Mediterranean diet is no exception to that rule. The Mediterranean Diet is not for everyone.
There may be some people who find that they have negative reactions to some of the foods on the diet others may find that it simply is not suitable for their lifestyle.
However, it is an excellent choice for most people because the health benefits are tremendous. Lower blood pressure, reduced cholesterol levels, reduced risk of diseases such as cancer, Alzheimer's, Parkinson's, diabetes and much more.
The diet is based on consuming wholesome fresh foods in their natural state and by cooking them in a healthy ways.
Red meats are eaten only on occasion; sugar, processed foods filled with additives, fast foods, and junk food, which are the cause of so many illnesses in today's world are simply not eaten.
It should not be news that most health problems in the US can be attributed to a poor diet and a sedentary lifestyle.
The Mediterranean diet solves both problems, if you let it. It provides the healthy nutritious foods your body needs for energy and well-being; plus, it incorporates exercise to solve the sedentary lifestyle issue.
Let's look at some of the potential difficulties.
1. The diet can be expensive.
When you eat primarily fish, fresh (preferably organic) fruits and vegetables, nuts, etc. you will find that they are more expensive than grabbing a cheeseburger from a fast food joint or buying junk food from the vending machine at work.
But . . . if you consider the health problems you may endure in the future and the cost of health care that goes with those problems, you may want to think twice about the actual cost. The healthy foods on the Mediterranean diet may not seem so expensive after all. Question: What provides healthy nutritious foods your body needs for energy?
Output: the Mediterranean diet
