We'll Give You an Exam Question, You Tell Us Which Class It's From

There's no actual consensus on how many parts of speech there are. A common number you'll hear is eight. This counts nouns, verbs, adjectives, adverbs, articles, prepositions, conjunctions and interjections.

This question would be found in a class on classical (Greek and Roman) mythology. The answer is Juno.

Pluto has teetered on the edge of planethood for a while now, with astronomers debating whether an object about 20 percent the size of Earth's moon can be called a planet. For now, it's a "dwarf planet."

Ralph Ellison wrote the classic "Invisible Man," about race and American culture. Don't confuse it with "The Invisible Man," a strictly sci-fi classic by H.G. Wells.

This is a basic (though impressive-sounding) biology question. The list goes: Kingdom, Phylum, Class, Order, Family, Genus and Species.

"Abnegation" means "putting aside or denying." (The root is "negation," and "ab" is a prefix meaning "away.") Don't use it interchangeably with "self-abnegation" -- you need the prefix for it to have that specific meaning.

The Missouri Compromise allowed MIssouri to enter the Union as a slave state. The "compromise" was that Maine was admitted as a free state.

The Punic Wars are something you'd study in world history. It's also a favorite name for students to alter by changing a letter in textbooks. (What? We were thinking "Panic Wars." What were you thinking?)

Hatshepsut was one of the female pharaohs of Egypt. She would be studied in a world history class, not European.

The Mason-Dixon line is commonly said to separate the northern U.S. from the South (though it doesn't extend across the country; not even into the Midwest). It was laid out by surveyors in the 18th century.

Compound interest is a fairly basic concept in economics. It might also be found in "life skills" courses.

This is more likely to be a government or civics question. But since the bill was signed into law several years ago, and Obama's presidency is now in the history books, it could also qualify as U.S. history.

Gravity causes acceleration of 9.8 feet per second squared. You learn this in physics class.

These are the three types of rock. Naturally, that makes this question fall under "geology."

"Lux" means "light" in Latin. It's a third-declension noun, so the "x" changes to a "c" as it's declined: lucis, luci, lucem, luce. From this we get our word "lucid," and others.

Lake Baikal, the world's deepest lake and possibly its oldest, is in Russia. So you'd study this in geography.

Atoms are also studied in physics, especially the subatomic particles and the field of quantum physics. However, you'll learn the basic part of the atom and how atoms behave in chemistry.

The U.S. Constitution was accepted by a majority of delegates on this date. This isn't the same thing as the individual states ratifying the document -- Rhode Island didn't officially ratify the Constitution until 1970!

A preposition shows a relationship between nouns. Over, under, by, around ... these are all prepositions.

"Pianoforte" is a term in music meaning "starting softly, then growing louder." Since it's Italian, you might learn it in Grammar as well as in Italian class.

The sentence above has a subject-verb agreement problem (which you probably knew). This falls under English, and more specifically, grammar.

"Beurre" is the French word for "butter." You'll want to know this if you're taking a trip to France that's centered on enjoying the food.

Caravaggio was a talented, controversial artist. His full name was Michelangelo Merisi da Caravaggio, and he is always called "Caravaggio" to avoid confusion with Michelangelo, the artist behind the Sistine Chapel.

Though the name might remind you of "Vietnam," Surinam is in South America. It used to be called Dutch Guyana.

The noble gases are a group of elements that are colorless, odorless and have very low reactivity. They include helium, argon and neon.

If you've followed the Diet Wars over the past ten years, you know what macronutrients are: carbohydrate, protein and fat/lipid. (Actually, there's a fourth, alcohol, but it's rarely mentioned). This is clearly a nutrition question, but you might also learn it in home economics, which nowadays covers how to be a well-educated grocery consumer and home cook.

"Beats" and "measures" are the province of music class. Often, the first beat in a measure is called the "downbeat."
