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: Amos reflects back on his early childhood in then British Mandate of Palestine (now Israel) with his mother Fania and father Arieh. His parents are Eastern European Jews living in Jerusalem, which his mother finds difficult as her sisters and family live in Tel Aviv and communication between them is difficult. Amos, an only child, is particularly close with his mother, who frequently tells him stories based on her childhood that often have unhappy or violent endings.
Amos' parents regularly lend him out to a childless couple they are friends with. On one occasion this couple take him to visit a friend of theirs, a Palestinian Arab. They warn Amos to be quiet and not make much fuss lest he offend their hosts, but while playing with a swing he accidentally injures a child.
On November 29, 1947, Amos' family and others from the neighbourhood gather around a radio in the street to hear the passing of United Nations General Assembly Resolution 181, which adopted a plan to partition Mandatory Palestine into independent Arab and Jewish states. Amos' parents are overwhelmed with joy. Soon afterwards, civil war erupts in Palestine. Amos' father enlists to fight in the 1948 Arab–Israeli War, while Amos and other children are recruited to the war effort. One of his mother's friends is killed while hanging up laundry during the war.
Fania falls into a depression and becomes unable to sleep or eat. Amos and Arieh try their best to hide her depression from their friends and family. After a change in pills Fania abruptly becomes her old more lively self and tries to act normally for her husband and child. A short time later she relapses once more and goes to visit her sisters in Tel Aviv, where she kills herself by overdose.
Amos goes to live on a kibbutz. Reuniting with his father as a teenager, he shows him his new life but admits that despite his attempts at being a strong and healthy farmer he is still a pale and weak intellectual.
What are the names of the people that the childless couple are friends with?
