Not too long after we arrived and unpacked, we were invited for "a drink on Sunday morning" by a retired couple nearby. We got there about noon, to find the living-room crowded -- lots of chat and discussions, and in all a very jolly occasion. Trouble was, there was no food -- no self-respecting Australian would regard a tray of crisps as food. In Sydney, when you are invited for a drink any time after midday on a Sunday, you know you will be fed as well as watered and you plan accordingly. Meaning the hardworked little woman makes no plans to cook lunch because you are eating out. By one-fifteen my stomach was sending up "please explain" to me. Even the crisps had gone. There was nothing we could do except wait, and wonder if the hostess was going to perform some magic and feed us fashionably late. Then, as quickly as if word had spread that there was free beer at the local pub, the room emptied. By one-forty-five there were only a few guests left, so we decided to go home. Tinned soup for lunch that day because the little woman was not really interested in real cooking for us. A few weeks ago we were invited out for "supper" and the hostess suggested 8:15. Ah, we thought greedily, "this is going to be the real thing." We dressed with some care -- I putting on a dark suit -- and arrived on time. My wife looked pretty good, I thought, a little black dress and so on. But when we walked in I had a terrible feeling we had got the night wrong because the hostess was dressed in a daytime kind of way and the husband was in jeans and an open-neck shirt. But no, we were greeted and shown into the sitting-room. After a drink I looked around and saw that this was indeed a superior cottage because it had a (more or less) separate dining-room. But there were no signs of a table-setting. Not again! I thought. Were we meant to eat before we came? I decided that in future my wife and I would...

Options: A: the hostess decided to feed her guests B: everyone had tinned soup for lunch C: most of the guests went to lunch at the pub D: the author realized he would go home hungry

Garrett Peterson, now 18 months old, was born with tracheomalacia , leaving him unable to breathe. The condition terrified his parents, who turned to specialist Dr. Glenn Green at the University of Michigan for a possible treatment. Along with Scott Hollister, a biomedical engineer who runs the university's 3-D printing lab, Green designed a device that can hold open Garrett's windpipe until it's strong enough to function independently. After taking a CT scan of Garrett's windpipe to make a replica of it, they made the "splint" with a 3-D printer. "It's like a protective shell that goes on the outside of the windpipe, and it allows the windpipe to be tacked to the inside of that shell to open it up directly," Green told NPR. On January 31, Garrett had his surgery. Surgeon Dr. Richard Ohye opened up Garrett's chest and saw that his windpipe had completely collapsed and one of his lungs was completely white -- a condition Ohye had only seen in dead bodies. After eight hours of surgery and careful placement of a splint on either side of Garrett's windpipe, it was time for the big test: What would happen when they let air flow through the windpipe into Garrett's lungs? Though he still remains in the hospital, Garrett has gotten stronger and needs less assistance breathing in the weeks since his surgery. His parents are overjoyed, saying he's starting to act more interactive and alert. As Garrett grows, the splint will expand and eventually dissolve in his body as his own windpipe strengthens enough to work independently. 3-D printing technology has allowed doctors to help patients in ways that they hope will continue to grow. "We're talking about taking something like dust and converting it into body parts," Green said. "And we're able to do things that were never possible before." Question: According to the passage, doctors' attitude toward 3-D printing technology in medical care is _ . Options: A: positive B: negative C: unknown D: indifferent
