A “Black Hole “is a body in space which does not allow any...
A black hole's property of not allowing any radiation to come out is due to its extremely high density. The gravitational pull of a black hole is so strong that not even light can escape from it, resulting in its characteristic feature of being "black" or devoid of any observable radiation. Therefore, option (c) is the correct choice.

I first met Max threesummers ago when he showed up at the park on the firstday of camp with his mother Katherine. After a brief(5) good morning, he went off to play with the rest of thefive and six year olds who I would be counseling for thenext several weeks. As his mother walked back to hercar, I couldn’t help but notice that she looked as thoughshe had just finished running a marathon; however, that(10) thought left my mind soon after she drove away, as Iwas surrounded by the smiling faces of thirty brandnew campers.The summer started off great, and Max and I hit itoff right away; he looked up to me as an older brother,(15) and I thought he was a great little kid. There were afew things that stuck out in my mind as odd, though,like when he would complain of being hungry an houror so after lunch at least once or twice a week. By thethird week of camp, I decided that it was something(20) I needed to investigate, and during lunch time I wentover to his table and asked if I could sit next to him.He giggled and said, “Sure Jake,” feeling special thatI would want to spend my lunch break with him. Hislunch consisted of a bag of potato chips, a can of soda,(25) and a chocolate bar—hardly a healthy meal for a fiveyear old. I offered him half of my sandwich and hiseyes lit up like it was his birthday.That afternoon, when Katherine came to pick Maxup from the park, I pulled her aside to discuss the lunch(30) issue.“Katherine, Maxwell needs to have a healthylunch.” She looked down at the ground.“What do you mean, Jake?”“I mean Max can not keep eating junk food(35) every day.”“Oh. That. I’m sorry about that. It’s just that Iwork back-to-back jobs every night and barely make ithome in time to get him out of bed and dressed beforecamp starts in the morning. His babysitter is supposed(40) to pack Max’s lunch for him at night when she putshim to bed. We have had a couple of new babysitterslately, and sometimes they forget to do it, so I end uphaving to throw something together at the last minute.I’ll make sure it doesn’t happen any more.”(45) “It happens to the best of us; I just wanted tomake sure you knew what he was eating. After a coupledays of him being hungry I got worried and wonderedwho was making his lunch for him. See you tomorrowmorning then.”(50) Several days later I expected to see Max eatinga sandwich went I went over to him atlunchtime. His lunch once again consisted entirely of junk food. Some-thing had to change; at the very least he needed to beeating much less sugar.(55) “Katherine,” I called to his mother as she steppedout of her car that afternoon. I really had no idea whatI was supposed to say. It was quite a predicament. “Wereally need to fix this problem with Max’s lunch.”“Jake, I know, it’s just that the house payment was(60) due yesterday, and I haven’t had the, uh, timeto get to the grocery store,” she trailed off. “Things are justa little hard for us right now.”She was obviously self-conscious at the moment, andI felt bad for having brought it up again. I told(65) her that I had a plan, and not to worry about it. Afterexplaining what I meant, the look on her face was oneof relief and thanks, and she and Max headed home forthe day.For the rest of the summer, I spent my lunches(70) with Max and his friends, having meetings of what wecalled the “Sandwich Club”: every day I would bring acouple of extra sandwiches, and anybody who wantedto try one could have some. Max never seemed to carewhat kind of sandwiches I brought to the club, but just(75) giggled and smiled up at me every afternoon.At the end of the summer, I got a letter fromKatherine, thanking me for being so kind to she andMax. I wrote back telling her that I could hardly waituntil the next meeting of the “Sandwich Club,” and to(80) tell Max that I said hello.For the next two years, the “Sandwich Club” hadregular meetings, Monday-Friday at noon, all summerlong. After that, Max and his mother moved to be closerto his grandparents, and I went back to having my lunch(85) with the rest of the staff. But for those few years, the“Summer Sandwich Club” brought joy to one campcounselor and many young campers.Q.The idea that Jake’s mother is trying her best to take care of her son is least supported by which of the following quotations from the passage?
