What do flextime and flexplace have in common? both allow you to work alternative hours. both are work accommodations. both allow you to work at a different location. all of the above

I would say that the correct answer is that both are work accommodations.
They don't both offer alternative hours - only flextime does, whereas flexplace offers you the opportunity to work from a place of your choosing - for example, a cafe, or your home. Only flexplace allows you to work at a different location - flextime doesn't; you still have to go to your office to work, but you can choose when. And finally, the last option is also incorrect. 

Though I do not have the answer, here's the story for anyone who hasn't seen it.

Explanation:

1 At the first yearbook meeting, I quietly sat in the back of the classroom and hardly said anything. Unlike the other yearbook-club members, I found it hard to come up with catchy slogans to put under the pictures. While some students were outgoing and had no difficulty signing up sponsors on a daily basis, I was afraid to ask my grandmother, who owned a business in our hometown. When I finally did work up the nerve to ask her for a donation, she offered me some advice.

2 She explained that she had been the photographer of her high-school yearbook. She pulled out the old crimson book and opened it up to a giant photograph that took up a whole page. A small group of kids crowded into the shot. I looked away from the photograph and up at my grandmother’s sentimental smile.

3 After she showed me some of her finest shots, we went up to her attic and found her old box of high-school memories. Inside, we found a letterman jacket that Grandma let me wear while we shuffled through the mementos. Finally, we found what she was searching for. At the bottom of the box was my Grandma’s big black camera. She explained that the strap was actually for a guitar. She had attached it to the camera so she could stylishly carry it around school. Again, her gorgeous smile expanded across her face as she remembered aloud.

4 I slipped the camera over my shoulders, and Grandma took me to purchase film. Then, she dropped me off at home, and I spent the rest of the weekend sauntering around my backyard taking photos of weird bugs and pretty flowers. By Monday morning, I felt like an experienced shutterbug ready to capture my classmates in my viewfinder.

In homeroom, I shot my class making goofy faces at my camera. In first period, I asked Mrs. Greene to pose with the students writing their homework problems on the board. She was a little shy at first, but with a little bit of coaxing, I got her to laugh as the students worked behind her. At lunch, I got the cafeteria workers to take a break and pose for a photograph. After I shot that one, I ordered a tuna melt, and as the cafeteria worker gave it to me, she leaned down and said, “Thanks for including us in your yearbook pictures.”

She made me feel so good that I kept shooting photographs all week. The next weekend, my mom and I developed the photos. Grandma’s camera sure was spectacular. I felt proud as I appreciated the clear genuine smiles beaming back at me. Grandma said that I was an amazing photographer, and I had to admit that I really captured the spirit of the people in my pictures. At the next yearbook meeting, I walked confidently into the classroom ready to share my photographs with the rest of the group.
