You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In Bad, Jackson's concept of the predatory lover is seen on the rock song "Dirty Diana". The lead single "I Just Can't Stop Loving You" is a traditional love ballad, and "Man in the Mirror" is a ballad of confession and resolution. "Smooth Criminal" is an evocation of bloody assault, rape and likely murder. AllMusic's Stephen Thomas Erlewine states that Dangerous presents Jackson as a paradoxical person. The first half of the record is dedicated to new jack swing, including songs like "Jam" and "Remember the Time". It was the first Jackson album in which social ills became a primary theme; "Why You Wanna Trip on Me", for example, protests world hunger, AIDS, homelessness and drugs. Dangerous contains sexually charged songs such as "In the Closet". The title track continues the theme of the predatory lover and compulsive desire. The second half includes introspective, pop-gospel anthems such as "Will You Be There", "Heal the World" and "Keep the Faith". In the ballad "Gone Too Soon", Jackson gives tribute to Ryan White and the plight of those with AIDS.HIStory creates an atmosphere of paranoia. In the new jack swing-funk rock tracks "Scream" and "Tabloid Junkie", and the R&B ballad "You Are Not Alone", Jackson retaliates against the injustice and isolation he feels, and directs his anger at the media. In the introspective ballad "Stranger in Moscow", Jackson laments his "fall from grace"; "Earth Song", "Childhood", "Little Susie" and "Smile" are operatic pop songs. In the "D.S.", Jackson launched a verbal attack against the lawyer Tom Sneddon, who had prosecuted him in both child sexual abuse cases. He describes Sneddon as an antisocial white supremacist who wanted to "get my ass, dead or alive". Sneddon said he had not listened to the song. Invincible was produced by Rodney Jerkins. It includes urban soul tracks such as "Cry" and "The Lost Children", ballads such as "Speechless", "Break of Dawn", and "Butterflies" and mixes hip hop, pop, and R&B in "2000 Watts", "Heartbreaker" and "Invincible".

What is the name of the first Jackson album in which social ills became a primary theme?
