In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

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 whose hand Lorna reaches for and realizes she is falling for?
Drake.

Passage: "The Thing That Should Not Be" was inspired by the Cthulhu Mythos created by famed horror writer H.P. Lovecraft, with notable direct references to The Shadow Over Innsmouth and to Cthulhu himself, who is the subject matter of the song's chorus.  It is considered the heaviest track on the album, with the main riff emulating a beast dragging itself into the sea. The Black Sabbath-influenced guitars are downtuned, creating slow and moody ambiance. "Welcome Home (Sanitarium)" was based on Ken Kesey's novel One Flew Over the Cuckoo's Nest and conveys the thoughts of a patient unjustly caged in a mental institution. The song opens with a section of clean single strings and harmonics. The clean, arpeggiated main riff is played in alternating 44 and 64 time signatures. The song is structured with alternating somber clean guitars in the verses, and distorted heavy riffing in the choruses, unfolding into an aggressive finale. This structure follows a pattern of power ballads Metallica set with "Fade to Black" on Ride the Lightning and would revisit with "One" on ...And Justice for All."Disposable Heroes" is an anti-war song about a young soldier whose fate is controlled by his superiors. With sections performed at 220 beats per minute, it is one of the most intense tracks on the record. The guitar passage at the end of each verse was Hammett's imitation of the sort of music he found in war films. The syncopated riffing of "Leper Messiah" challenges the hypocrisy of the televangelism that emerged in the 1980s. The song describes how people are willingly turned into blind religious followers who mindlessly do whatever they are told. The 136 beats per minute mid-tempo riffing of the verses culminates in a descending chromatic riff in the chorus; it increases to a galloping 184 beats per minute for the middle section that climaxes in a distorted scream of "Lie!". The title derives from the lyrics to the David Bowie song "Ziggy Stardust". "Orion" is a multipart instrumental highlighting Burton's bass playing. It opens with a fade-in bass section, heavily processed to resemble an orchestra. It continues with mid-tempo riffing, followed by a bass solo at half-tempo. The tempo accelerates during the latter part, and ends with music fading out. Burton arranged the middle section, which features its moody bass line and multipart guitar harmonies. "Damage, Inc." rants about senseless violence and reprisal at an unspecified target. It starts with a series of reversed bass chords based on the chorale prelude of Bach's "Come, Sweet Death". The song then jumps into a rapid rhythm with a pedal-point riff in E that Hammett says was influenced by Deep Purple. 
Question: What song is structured with alternating somber clean guitars in the verses, and distorted heavy riffing in the choruses?

Welcome Home (Sanitarium).
