PROBLEM: Passage: A NASA spacecraft lands on an unknown planet and begins to take rock and soil samples. Four aliens discover it and are sucked into the craft through its vacuum tube, after which it makes its way back to Earth. The aliens are able to escape from a government base by using their powers (with which they can destroy or heal anything they touch). During the escape, the youngest one hides in a passing van, occupied by a boy named Eric Cruise who uses a wheelchair, his older brother, Michael, and their single mother, Janet, who are moving to California from Illinois.
Shortly after the Cruise family arrives at their new home, Eric becomes suspicious of the alien's presence. The next morning, he finds that the creature has trashed most of the house and learns its identity, but is blamed alongside his brother by their mother for what has happened. After seeing the creature again, Eric tries to catch up to him, but ends up sliding down a hill and falls into a lake, where he nearly drowns, but is rescued by the alien. Eric is not believed at all when he tries to tell his family about the creature's actions.
Later that night, he sets a trap with the help of his new friend, Debbie, who had also seen the alien. The two trap him inside a vacuum cleaner, which malfunctions and causes the entire neighborhood to suffer a power surge. After the alien is released, Michael now believes Eric, but it leaves before Janet can be convinced. Eric's behavior towards the alien changes after he fixes all of the damage he caused to the house, and leaves behind several newspaper clippings which Eric believes are an attempt to communicate. 
Question: Who is attempting to communicate with Eric?

SOLUTION: the alien.

PROBLEM: Passage: Hotshot ensign Alan Drake, fresh from the flying academy at Pensacola, Florida, gets off to a bad start with the pilots of an elite squadron, nicknamed the "Hellcats", to which he has been posted in San Diego. Making a nearly disastrous landing attempt in heavy fog against orders and disqualifying the squadron during a competitive shooting exercise by colliding with the target drogue does not endear him to his fellow pilots. He also asks out a woman he has met, Lorna, not knowing that she is the squadron commander Billy Gary's (Walter Pidgeon) wife.
However, Drake is earnest and contrite. He mixes with the Hellcats at the Garys' large house, which the sociable couple have opened as an unofficial officers' club. His flying and his social errors are forgiven, and his fellow pilots accept him, nicknaming him "Pensacola". 
Drake further proves himself when he helps Lieutenant Jerry Banning solve a problem in a blind-landing apparatus he is developing. Just after Commander Gary is sent out of town on assignment, Banning decides the apparatus is ready to test in fog — but it fails and Banning is killed. Working with Banning's assistant, Drake soon identifies the problem, but no further testing is allowed until Commander Gary's return.
Banning had been a childhood friend of Lorna Gary, and is not her first friend to die. She sinks into a deep depression. She also knows that Gary will expect her to hide her feelings and carry on, something that is very much not in her nature. Drake, appreciating the help the Garys gave him when he arrived, visits her at her home, and convinces her she should not suffer alone. They go for walks, drives, and tennis; he amuses her with jokes. Finally, at a restaurant she reaches for his hand and in doing so realizes she is falling for him. She quickly breaks away, and says she cannot see him any more. 
Question: What is the last name of the person that Lorna realizes that she can't see anymore?

SOLUTION: Drake.

PROBLEM: Passage: The story begins when Heidi, a little five-year-old girl, is brought up to the Swiss Alps by her Aunt Dete, who took care of the little girl ever since the passing of her two parents. Dete leaves Heidi with her grandfather, who lives alone up in the mountains, and though at first the old man refuses, Dete insists and he finally agrees to take her in but sends Dete away discourteously. Heidi's sweet, innocent nature slowly wins the heart of her grandfather and they soon grow fond of each other. Heidi wonders about every aspect of her new life in the mountains and has questions about all sorts of things. She befriends Peter, a young boy slightly older than she, whose job it is to lead the many goats up to the mountains every day. However, just as Heidi decides that she could never love anything more than life up in the mountains, Dete returns to take her away from her grandfather and to the city of Frankfurt in Germany, where she expects the girl to serve as a companion for the Sessemann's invalid daughter Clara. Though she misses her grandfather and the goats dearly, once in Frankfurt, Heidi becomes the best of friends with Clara and is saddened by her inability to walk. After many conflicts with Madam Rottenmeier, the strict care-taker at the Sesseman's, at her birthday party, Clara gives Heidi what she thinks she wants most: a train ticket to Switzerland, to her grandfather and old friends. Another surprise awaits Heidi and her grandfather as Clara and her grandmother come to visit them up at their home in the mountains. 
Question: Whose parents passed away?

SOLUTION:
Heidi.
