Question 1: Where is the famous archaeological site of "Terracotta Army" located?
Question 2: When was Leonardo da Vinci's "Mona Lisa" believed to have been completed?
"Mona Lisa" is one of the most famous paintings by Leonardo da Vinci and is thought to have been completed between 1503 and 1506, although Leonardo may have continued working on it as late as 1517. The painting is renowned for its detailed portrayal of Lisa Gherardini, its use of sfumato—a technique for softening the transition between colors—and its enigmatic expression.
Question 3: What is the psychological phenomenon where a person in a group is less likely to take action or feel a sense of responsibility?
The bystander effect was first demonstrated following the infamous case of Kitty Genovese's murder in 1964, where it was reported that 38 bystanders failed to intervene or call the police. However, research over the years has shown that this number was exaggerated and that some actions were taken by witnesses. The phenomenon has been heavily studied and is often explained by the diffusion of responsibility when more people are present.
Question 4: Where is most of an insect's skeletal system located?
An exoskeleton is a hard external skeleton that supports and protects an insect's body. It is made of chitin and protein and covers the insect's entire body surface. As the insect grows, it must periodically molt its exoskeleton and secrete a new larger one.
Question 5: How many years did it take to construct the Sydney Opera House?
The construction of the Sydney Opera House began in 1958 and was completed in 1973. Danish architect Jørn Utzon designed the iconic structure, which is renowned for its unique use of a series of white shell-shaped roofs.
Question 6: When did Australia first participate in the Olympics?
Australia has participated in all summer Olympic Games held since the first event in Athens in 1896. They have also participated in the winter Olympics since 1936.
Question 7: Which company introduced the first commercially available hybrid gasoline-electric car?
The Toyota Prius was introduced in Japan in 1997, and later globally in 2000. It was the world's first mass-produced hybrid car, combining a gasoline engine with an electric motor to increase fuel efficiency.
Question 8: Why is the popular cocktail "Bloody Mary" so named?
The Bloody Mary cocktail, made with vodka, tomato juice, and various spices, is named after Queen Mary I of England, who was nicknamed "Bloody Mary" due to her persecution of Protestants during her reign in the 16th century. The red color of the drink is said to symbolize the blood spilled during her reign.
Question 9: When is the Jewish New Year, or Rosh Hashanah, usually celebrated?
Rosh Hashanah marks the beginning of the Jewish High Holy Days or "Days of Awe" and is observed on the first two days of the Hebrew month of Tishrei, which falls during September or October. It’s a time for prayer and reflection, and customs include the sounding of the shofar (a ram's horn) and eating sweet foods for a sweet new year.
Question 10: What concept in physics defines the quantity of motion of a moving body, measured as a product of its mass and velocity?
Momentum is a fundamental concept in physics and is conserved in isolated systems, a principle known as the conservation of momentum. It is an important quantity because it is conserved in systems where there are no external forces acting, which helps physicists understand and predict the result of collisions and interactions.
Tough today. Lotsa guesses.
wow I’m happy with nine but damn I almost got question nine correct as well.
