For how many years did the Berlin Wall stand?
- 9
- 16
- 28
- 35
The Berlin Wall was a guarded concrete barrier that encircled West Berlin of the Federal Republic of Germany (FRG) from 1961 to 1989, separating it from East Berlin and the German Democratic Republic (GDR) for 28 years. Construction of the Berlin Wall was commenced by the government of the GDR on August 13, 1961. It included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails and other defenses. The primary intention for the Wall's construction was to prevent East German citizens from fleeing to the West.

A galactic or cosmic year measures the orbit of which celestial body?
- The Sun
- Saturn
- Neptune
- The Moon
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. One galactic year is approximately 225 million Earth years. The Solar System is traveling at an average speed of 143 mi/s within its trajectory around the Galactic Center, a speed at which an object could circumnavigate the Earth's equator in 2 minutes and 54 seconds; that speed corresponds to approximately 1/1300 of the speed of light.

How often does a leap year occur?
- Once every two years
- Once every four years
- Once every five years
- Once every ten years
Leap years happen when we add one day to the end of February in order to align our calendar with the Earth's orbit. Once every four years, we tack a 29th day onto the end of February, which is usually 28 days long, making a leap year 366 days instead of 365. We generally refer to 365 as the number of days it takes for the Earth to orbit the sun, but it actually takes 365.242190 days or 365 days, 5 hours, 48 minutes, and 56 seconds, to be exact. To compensate for using a rounded number the rest of the time, we add this extra day periodically to keep our calendar in line with our equinoxes, solstices, and seasons.

For how many years is an adult U.S. passport valid?
- 10 years
- 6 years
- 8 years
- 15 years
Ordinarily, a US passport is valid for 10 years for adults and five years for children under age 16. Your passport’s expiration date isn’t the only factor to consider when traveling internationally. Many countries require your passport to have a specific period of validity remaining. Since you cannot travel on an expired passport and it takes time to get a new passport, countries try to ensure visitors won't have any trouble getting back home should their planned departure be delayed. Many have adopted the six-month passport rule to avoid complications.

How long is a day on the Moon?
- 7 Earth days
- 12.5 hours
- 29.5 Earth days
- 365 Earth days
We know that the Moon is tidally locked with Earth, which means that one side is constantly facing toward it. But with one side facing the Earth and the other side facing out, what constitutes a single day on the lunar surface? To break it down simply, a day on the Moon lasts as long as 29.5 Earth days. In other words, if you were standing on the surface of the Moon, it would take 29.5 days for the Sun to move all the way across the sky and return to its original position again. Since ancient times, lunar calendars have been based on thirteen months of 28 days each, reflecting the lunar cycle.

How many days of seclusion are implied by the word "quarantine"?
- Fifty
- Thirty
- Twenty
- Forty
A quarantine is a restriction on the movement of people, animals, and goods that is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. The word quarantine comes from quarantena or quarantaine, meaning "forty days", used in the Venetian language in the 14th and 15th centuries and also in France.

The sun is one of about 100 billion stars in our galaxy, the Milky Way. It has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun’s heat and light, life on Earth would not exist. It is about 93 million miles from Earth, and it takes its light about 8 minutes to reach our planet.

How many hours does the average person spend dreaming each night?
- About 80 minutes
- About 15 minutes
- About one hour
- About two hours
Researchers estimate that the average person spends about two hours dreaming each night. However, dream content research relies on self-reported information, which can be unreliable. Also, not all people remember their dreams after waking. This memory gap makes it challenging for researchers to accurately estimate the duration of each dream or deduce whether the perceived length of a dream matches how long the dream actually lasted.

How many years does a "sesquicentennial" refer to?
- 60
- 100
- 150
- 160
A sesquicentennial is equal to 150 years - sesqui- (one and a half) centennial (100 years). Latin terms for anniversaries are mostly straightforward, particularly those relating to the first thirty years (1–30), or multiples of ten years (30, 40, 50, 60, 70 etc.), or multiples of centuries or millenniums (100, 200, 300, 1000, 2000, 3000, etc.) In these instances, the name of the anniversary is generally derived from the Latin word(s) for the respective number of years. When anniversaries relate to fractions of centuries (125, 150, 175, 225 years—i.e. 1.25, 1.5, 1.75, and 2.25 centuries), the situation is not as simple.

How many seconds are in an hour?
- 600
- 2,400
- 3,600
- 1,200
A second is our base unit of time—base, but not the smallest. A base unit is a unit defined on its own terms upon which other units are based. That means that all our other units, such as minutes, hours, nanoseconds, and so on, are all based on seconds. You may already know that there are 60 minutes in an hour, but how many seconds is that? To figure it out, we’ll need to multiply. 60 seconds in one minute and 60 minutes in one hour means that 1hour=60*60. Calculate that out and you’ll find that 1 hour = 3,600 seconds.
