In 1969, Schwarzenegger met Barbara Outland (later Barbara Outland Baker), an English teacher he lived with until 1974. Schwarzenegger talked about Barbara in his memoir in 1977: "Basically it came down to this: she was a well-balanced woman who wanted an ordinary, solid life, and I was not a well-balanced man, and hated the very idea of ordinary life." Baker has described Schwarzenegger as "[a] joyful personality, totally charismatic, adventurous, and athletic" but claims towards the end of the relationship he became "insufferable – classically conceited – the world revolved around him". Baker published her memoir in 2006, entitled Arnold and Me: In the Shadow of the Austrian Oak. Although Baker, at times, painted an unflattering portrait of her former lover, Schwarzenegger actually contributed to the tell-all book with a foreword, and also met with Baker for three hours. Baker claims, for example, that she only learned of his being unfaithful after they split, and talks of a turbulent and passionate love life. Schwarzenegger has made it clear that their respective recollection of events can differ. The couple first met six to eight months after his arrival in the U.S – their first date was watching the first Apollo Moon landing on television. They shared an apartment in Santa Monica for three and a half years, and having little money, would visit the beach all day, or have barbecues in the back yard. Although Baker claims that when she first met him, he had "little understanding of polite society" and she found him a turn-off, she says, "He's as much a self-made man as it's possible to be – he never got encouragement from his parents, his family, his brother. He just had this huge determination to prove himself, and that was very attractive … I'll go to my grave knowing Arnold loved me."

What historical event did Baker and Schwarzenegger watch on TV together on their first date?
Answer: the first Apollo Moon landing


Problem: In 680 Ibn al-Zubayr fled Medina for Mecca. Hearing about Husayn's opposition to Yazid I, the people of Kufa sent to Husayn asking him to take over with their support. Al-Husayn sent his cousin Muslim bin Agail to verify if they would rally behind him. When the news reached Yazid I, he sent Ubayd-Allah bin Ziyad, ruler of Basrah, with the instruction to prevent the people of Kufa rallying behind Al-Husayn. Ubayd-Allah bin Ziyad managed to disperse the crowd that gathered around Muslim bin Agail and captured him. Realizing Ubayd-Allah bin Ziyad had been instructed to prevent Husayn from establishing support in Kufa, Muslim bin Agail requested a message to be sent to Husayn to prevent his immigration to Kufa. The request was denied and Ubayd-Allah bin Ziyad killed Muslim bin Agail. While Ibn al-Zubayr would stay in Mecca until his death, Husayn decided to travel on to Kufa with his family, unaware of the lack of support there. Husayn and his family were intercepted by Yazid I's forces led by Amru bin Saad, Shamar bin Thi Al-Joshan, and Hussain bin Tamim, who fought Al-Husayn and his male family members until they were killed. There were 200 people in Husayn's caravan, many of whom were women, including his sisters, wives, daughters and their children. The women and children from Husayn's camp were taken as prisoners of war and led back to Damascus to be presented to Yazid I. They remained imprisoned until public opinion turned against him as word of Husayn's death and his family's capture spread. They were then granted passage back to Medina. The sole adult male survivor from the caravan was Ali ibn Husayn who was with fever too ill to fight when the caravan was attacked.
What did Ubayd-Allah bin Ziyad rule?
The answer is the following: Basrah


Thus, in less than twenty years, Rome had destroyed the power of one of the successor states, crippled another, and firmly entrenched its influence over Greece. This was primarily a result of the over-ambition of the Macedonian kings, and their unintended provocation of Rome; though Rome was quick to exploit the situation. In another twenty years, the Macedonian kingdom was no more. Seeking to re-assert Macedonian power and Greek independence, Philip V's son Perseus incurred the wrath of the Romans, resulting in the Third Macedonian War (171–168 BC). Victorious, the Romans abolished the Macedonian kingdom, replacing it with four puppet republics; these lasted a further twenty years before Macedon was formally annexed as a Roman province (146 BC) after yet another rebellion under Andriscus. Rome now demanded that the Achaean League, the last stronghold of Greek independence, be dissolved. The Achaeans refused and declared war on Rome. Most of the Greek cities rallied to the Achaeans' side, even slaves were freed to fight for Greek independence. The Roman consul Lucius Mummius advanced from Macedonia and defeated the Greeks at Corinth, which was razed to the ground. In 146 BC, the Greek peninsula, though not the islands, became a Roman protectorate. Roman taxes were imposed, except in Athens and Sparta, and all the cities had to accept rule by Rome's local allies.
When did the Greek peninsula become a Roman protectorate?
146 BC


Problem: Please answer a question about the following article about Solar energy:
Thermal mass is any material that can be used to store heat—heat from the Sun in the case of solar energy. Common thermal mass materials include stone, cement and water. Historically they have been used in arid climates or warm temperate regions to keep buildings cool by absorbing solar energy during the day and radiating stored heat to the cooler atmosphere at night. However, they can be used in cold temperate areas to maintain warmth as well. The size and placement of thermal mass depend on several factors such as climate, daylighting and shading conditions. When properly incorporated, thermal mass maintains space temperatures in a comfortable range and reduces the need for auxiliary heating and cooling equipment.
What does thermal mass reduce the need for?
A:
auxiliary heating and cooling equipment
