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

Example Input: I was 35 weeks pregnant when I had my stroke. For weeks prior to the event I kept experiencing 'visual disturbances.' I felt when I was reading a newspaper or book a sense that my eyes were crossing. I'd feel aware right before it would occur and I would rush to look in a mirror only to discover my eyes were not crossing. I informed my OB who blamed it on the blood vessels in my eyes enlarging due to pregnancy. Ummm ok. You know more than me. Later I was told by a surgeon what I was experiencing was 'textbook' for the passing of blood clots through my occipital area of the brain!
The feeling would eventually subside. I awoke one morning feeling 'kind of fuzzy' headed. Like I had slept too hard. I sat with my husband at the kitchen table for our morning coffee and newspaper and for no reason I could imagine I was unable to swallow my coffee and it dribbled out the left side of my mouth. My husband asked me what was going on and I apparently told him, I was 'stroking' out. He got up from the table assuming I was OK and went off to take his morning shower. While in the shower it occurred to him something might not be right. He came back to the table where I was struggling to lift myself from the chair. I put my hands on the table to lift my body and my left hand kept sliding off the edge. He finally got behind me and tried to lift me under my arms and I crumbled to the floor. He then called my OB and told him he thought I'd had a stroke. My OB immediately expressed his doubt but my husband was advised to call an ambulance to get me to the ER. I never really experienced pain from the stroke. Question: Who told the narrator that they were experiencing "textbook" symptoms of a blood clot?
Example Output: The surgeon

Example Input: Macy Golong peeked into Mallie Mae's room and was not surprised to see her sleeping. Elmo's mother rarely stayed up past 10:00 PM, and it was nearly 11:00. She closed the door and started to go back to her room across the hall. She was halfway through a romance novel. But Hadley's delicious oatmeal raisin cookies were calling to her.
She walked down the stairs to the kitchen and put a few cookies on a plate. Then she poured a glass of milk. She wondered what Elmo was doing. Was he in the Media Room with Carsie? Their Media Room? Before Elmo and Carsie got together, Elmo and Macy used to spend hours almost every night in that room. Some nights he had almost kissed her.
She left her milk and cookies on the kitchen counter and went down another flight of stairs, which came out in the Recreation Room. Macy could hear the sound of the TV coming from Media Room. She tiptoed to the open doorway and peeked in. There she was--that conniving slut--sitting where Macy should have been. How could Elmo have replaced her like that? She thought he had been falling in love with her. How could she have been so wrong? But it could still happen--if that woman would just go away.
Elmo said, "Yeah. So, beginning Monday there will be two doctors in the office. That should take a little pressure off. If I need to be out for a day or two, Dr. Edwards can fill in for me."
"Yeah, or if you need to take off a week for a trip to Hawaii with your beautiful new wife." Carsie gave him a sexy smile.
"That's right. Dr. Ernie will take care of everything while I'm gone."
"Dr. Ernie?"
"Yeah. I asked if he would mind being called 'Dr. Ernie'. His name is Ernest, but I thought 'Dr. Ernie' would fit in well with the Sesame Street theme of my office."
"So the two of you are Drs. Elmo and Ernie?"
"Yep." Question: Who rarely stayed up past 10:00 pm?
Example Output: Elmo's Mother

Example Input: Former President Barack Obama unveiled plans for his future presidential library and museum on the south side of Chicago where he raised his family and launched his political career.
The designs show a complex of modern buildings, with a library, museum and event center, plus a community garden, a children's play area and possibly an athletic field.
"What we want this to be is the world-premiere institution for training young people and leadership to make a difference in their communities, in their countries and in the world," he told the crowd that included Chicago Mayor Rahm Emanuel, his one-time chief of staff.
Flanked by drawings and renderings, Obama also announced that he and former first lady Michelle Obama will be donating $2 million to fund a Chicago summer jobs program.
The museum, the tallest of the three buildings, will hold exhibition space, public spaces, offices and education and meeting rooms, according to the Obama Foundation. The forum and library buildings are intended to be used for study and foundation programming. Obama said his foundation, which is overseeing the project, is also looking into the possibility of locating a Chicago Public Library branch on the site.
Obama said he envisioned recording studios where musicians could help young people work on music, and space for movie directors who could take on community storytelling. The center will also have exhibits with campaign memorabilia and personal artifacts.
"Let's face it, we want to see Michelle's dresses," the former president joked.
Obama also squashed any notion that the library was ever going to be elsewhere. Multiple locations in three states Illinois, New York and Hawaii had initially pitched proposals.
"The best things that have happened to me in my life happened in this community," he said. "Although we had a formal bidding process to determine where the presidential library was going to be, the fact of the matter was it had to be right here on the south side of Chicago." Question: Who announced the building of a presidential library in Chicago?
Example Output:
Former president Barack Obama.
