When I was six, Dad brought home a dog one day, who was called "Brownie". My brothers and I all loved Brownie and did different things writh her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games, Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them, we always felt better when she was around.
One day, as I was getting her food, she chewed up one of Dad’s shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, "Bad girl," she looked down at the ground and then went and hide. I saw a tear in her eyes.
Brownie turned out to be more than just our family pet, she went everywhere with us. People would stop and ask if they could pet her. Of course she’d let anyone pet her. She was just the most lovable dog. There were many times when we’d be out walking and a small child would come over and pull on her hair. She never barked or tried to get away. Funny thing is she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loved everyone.
Now many years have passed since Brownie died of old age. I still miss days when she was with us.

A:would eat anything when hungry B:felt sorry for her mistake C:loved playing hide-and-seek D:disliked the author’s dad

In an interview last month, Frank Church, chairman of the Senate committee that is investigating the CIA, issued an oblique but impassioned warning, that the technology of eavesdropping had become so highly developed that Americans might soon be left with "no place to hide". That day may have arrived. Newsweek has learned that the country’s most secret intelligence operation, the National Security Agency, already possesses the computerized equipment to monitor nearly all overseas telephone calls and most domestic and international printed messages.
The agency’s devices monitor thousands of telephone circuits, cable lines and the microwave transmissons that carry an increasing share of both spoken and written communications. Computers are programed to watch for "trigger" words or phrases indicating that a message might interest intelligence analysis, when the trigger is pulled, entire messages are tape-recorded or printed out.
That kind of eavesdropping is, however, relatively simple compared with the breakthroughs that lie ahead in the field of snoopery. Already it is technically feasible to "bug" an electric typewriter by picking up its feeble electronic emissions from a remote location and then translating them into words. And some scientists believe that it may be possible in the future for remote electronic equipment to intercept and "read" human brain waves.
Where such capabilities exist, so too does the potential for abuse. It is the old story of technology rushing forward with some new wonder, before the man who supposedly control the machines have figure out how to prevent the machines from controlling them.
Which is the best title for the passage

A:Fight Against Eavesdropping B:A New Breakthrouth C:No Place to Hide D:An Impassioned Warning
