Ostriches are the fastest-running birds, capable of reaching speeds up to 70 kilometers per hour (43 miles per hour). Their long, powerful legs and specialized anatomy allow them to cover significant distances with each stride. This speed is crucial for survival in their native African savannas, where they need to outrun predators like lions and cheetahs.

Neil Armstrong was the first person to step foot on the moon. This historic event occurred on July 20, 1969, during the Apollo 11 mission. Armstrong, along with Buzz Aldrin, landed the lunar module Eagle on the moon's surface and Armstrong became the first human to set foot on another celestial body. His famous words, "That's one small step for man, one giant leap for mankind," will always be remembered as a monumental achievement in human history.

To calculate the total number of minutes in 3 hours and 45 minutes:

Convert hours to minutes:

3 hours = 3 × 60 = 180 minutes

Add the extra minutes:

180 minutes (from 3 hours) + 45 minutes = 225 minutes

So, the total is 225 minutes.

The Grand Canyon is a breathtaking natural wonder located in northern Arizona, known for its immense size, vibrant layers of rock, and geological significance. Stretching approximately 277 miles (446 km) in length, up to 18 miles (29 km) in width, and over a mile (1.6 km) deep, it reveals nearly 2 billion years of Earth's geological history. The Colorado River carved the canyon over millions of years, and it continues to flow through it today.

A triangle is a polygon with three sides and three angles. The reason the sum of the angles to 180 degrees can be understood using geometric principles. If you draw a straight line (which measures 180 degrees) and then form a triangle by connecting points along this line and adding a third point above or below, the angles of the triangle will always combine to make a straight line. In non-Euclidean geometry, such as on a curved surface, this rule may not apply, but for standard geometry, the sum of the angles is always 180 degrees.

The area of a square is found by multiplying the length of one side by itself (squaring the side). Since the square has a side of 5 cm, we calculate 5 cm * 5 cm. This gives us 25 square cm, which is the total area covered by the square.

Brazil is the largest South American country by area. It covers a vast landmass, spanning over 8.5 million square kilometers. With its expansive territory, Brazil surpasses other South American countries like Argentina, Chile, Mexico, and Peru in terms of size.

The American Civil War is the correct answer because it was a war that occurred between the Union and the Confederacy. This war took place from 1861 to 1865 and was fought over issues such as slavery, states' rights, and the preservation of the Union. It was a significant event in American history and resulted in the abolition of slavery and the reunification of the United States.

A heptagon is a geometric shape with seven sides and seven angles. It is classified as a polygon, which is any closed shape with straight sides. Each of the seven angles in a regular heptagon is equal, making it a symmetrical shape. The term "heptagon" comes from the Greek words "hepta," meaning seven, and "gonia," meaning angle. Heptagons can be found in various mathematical and architectural contexts.

The American President John F. Kennedy was assassinated on November 22, 1963. He was shot while riding in a motorcade in Dallas, Texas, and his assassination is one of the most significant and tragic events in American history. The incident shocked the nation and the world, leading to various investigations and conspiracy theories regarding the circumstances of his death.

17 is the only prime number among the given options. A prime number is a number that is only divisible by 1 and itself, and 17 fits this criteria as it is not divisible by any other number. The other numbers in the options, such as 8, 30, 63, and 99, are all divisible by numbers other than 1 and themselves, making them composite numbers.

Brussels is not only the capital city of Belgium but also serves as the administrative center of the European Union, often referred to as the "capital of Europe." It is known for its historical architecture, vibrant culture, and significant role in international politics and diplomacy. Brussels has a rich and complex history that dates back over a thousand years. It was founded as a small fort on the Senne River around the 10th century and grew into an important economic and political hub during the medieval period.

The correct answer is South America because the Inca civilizations were primarily located in the Andes region of South America, specifically in present-day Peru, Ecuador, Bolivia, and parts of Colombia and Chile. The Inca Empire was the largest empire in pre-Columbian America and thrived in the 15th and 16th centuries. Their capital city, Cusco, was located in modern-day Peru. The Inca civilization is known for its advanced agricultural practices, impressive architecture, and extensive road network, including the famous Machu Picchu.

Jupiter is a gas giant with a diameter of approximately 143,000 kilometers (88,846 miles), making it the largest planet by both mass and volume. It is so massive that more than 1,300 Earths could fit inside it. Known for its Great Red Spot, a giant storm that has raged for centuries, and its many moons, Jupiter dominates the outer solar system.

A solar eclipse is a celestial event that occurs when the moon passes between the Earth and the sun, blocking some or all of the sun's light from reaching Earth. This results in a temporary darkening of the sky during the day as the moon casts a shadow on the Earth's surface. There are different types of solar eclipses, including total, partial, and annular, depending on the alignment of the sun, moon, and Earth. During a total solar eclipse, the sun is completely obscured by the moon, creating a dramatic and brief period of darkness in the daytime.

Georgia is a state that is not on the Gulf of Mexico, as it borders the Atlantic Ocean instead. In contrast, Texas, Florida, Alabama, and Louisiana all have coastlines along the Gulf of Mexico. These states are positioned along the southern edge of the United States, with varying lengths of coastline that connect to the Gulf. Its capital and largest city is Atlanta, a major cultural and economic hub in the region. Known as the "Peach State", Georgia has a diverse landscape that ranges from the Appalachian Mountains in the north to coastal plains in the south.

'Carefully' is an example of an adverb because it modifies the verb 'is' by describing how the action is performed. Adverbs typically provide information about how, when, where, or to what extent an action is done. In this case, 'carefully' tells us how something is being done, indicating the manner in which the action is performed.

Roman city planning followed a systematic approach, influenced by their military camp layouts (known as castra). These cities featured a rectangular grid of streets, with two main roads—the cardo (running north-south) and the decumanus (running east-west)—dividing the city into blocks or insulae. This grid structure made navigation and urban planning more efficient, and the design was used both in newly founded cities and Romanized areas throughout the empire. This organized layout was key to the functioning of Roman cities, facilitating trade, defense, and public services.

The autumnal equinox marks the moment when day and night are nearly equal in length, signaling the beginning of autumn. It typically happens around September 22 or 23 each year. This event is caused by the tilt of the Earth's axis and its orbit around the Sun, leading to the Sun crossing the celestial equator.

Members of the House of Representatives serve two-year terms. Elections for all 435 seats in the House are held every two years, during even-numbered years. Representatives can serve an unlimited number of terms if they continue to be re-elected by their constituents. This short term length was designed to keep Representatives closely connected to the changing opinions and needs of their constituents.

The Four Corners is a region in the southwestern United States where the boundaries of four states meet at a single point. These states are Arizona, Colorado, New Mexico, and Utah. Nevada, while geographically close, does not share a border with the other four states at the Four Corners Monument.

The smallest prime number is 2. It is the only even prime number, as all other even numbers can be divided by 2 and are therefore not prime. Prime numbers are natural numbers greater than 1 that are divisible by only 1 and themselves, and 2 fits this definition, making it the smallest prime number.
