Dr. Evans lives at 123 Main Street, Anytown, USA. When writing his title and address, which part contains a capitalization error?

Answer: 123 Main street

The names of specific streets are proper nouns and should be fully capitalized. Therefore, 'Main Street' should be capitalized, not 'Main street'. Titles like 'Dr.', names of people, cities, and countries are all capitalized correctly.

The mountain climber found the final ascent to be the most arduous part of the journey. Unlike the gentle slopes at the beginning, this last section was steep, icy, and required immense effort. Based on the context, which word is an antonym for 'arduous'?

A physician measured the medication in 10 milliliters. Which of the following comes closest to the amount of drugs the pharmacist measured in teaspoons? (5 milliliters in 1 teaspoon)

Answer: 2 teaspoons

The problem states that 5 milliliters (ml) is equivalent to 1 teaspoon. To convert 10 milliliters to teaspoons, you divide the total milliliters by the conversion factor. Therefore, 10 ml divided by 5 ml/teaspoon equals 2 teaspoons.

Which sentence correctly uses a semicolon?

Answer: I was tired; I finished my homework anyway.

A semicolon correctly joins two independent clauses without a coordinating conjunction.

If x + 8 = 15, what is the value of x?

A map of a fairground is laid out on a grid. The Ferris wheel is located in square B3. To find it, you should look for the square where:

Answer: Row 'B' and Column '3' intersect.

A map grid uses coordinates to pinpoint locations. You find the location by identifying the row designated by the letter ('B') and the column designated by the number ('3') and finding where they intersect.

Which sentence correctly uses a comma before a coordinating conjunction?

Answer: I wanted to go to the park, but it was raining.

Answer: 12

The smallest number divisible by both 4 and 6 is 12 (4×3 = 12, 6×2 = 12).

Which number sentence shows the distributive property?

Answer: 4 × (3 + 5) = (4 × 3) + (4 × 5)

The distributive property states that a × (b + c) = (a × b) + (a × c), which matches 4 × (3 + 5) = (4 × 3) + (4 × 5).
