According to the passage, which of the following can sometimes trigger an audit?

  • Making multiple Internet type purchases

  • Filing state income tax online

  • Making out-of-state purchases

  • Paying use tax when filing the state income tax return

Correct answer: Making multiple Internet type purchases

The passage’s last paragraph states: “If you have a lot of Internet type purchases of equipment for use in your business, sometimes these purchases can trigger an audit.” Therefore, the reader can determine that making multiple Internet-type purchases can sometimes trigger an audit.

The passage does not state that filing state income tax online, making out-of-state purchases, or paying use tax when filing the state income tax return would trigger an audit.

Identify the adjectives in the following sentence.

After she was bitten, Mary never again touched the big white dog.

  • big; white

  • after; bitten

  • Mary; dog

  • big; dog

Correct answer: big; white

After she was bitten, Mary never again touched the big white dog.

An adjective is a word or phrase naming an attribute, added to or grammatically related to a noun to modify or describe it. Both big and white are adjectives that act as modifiers for the noun dog.

In this sentence, after is a preposition, bitten is a verb, Mary is a noun, and dog is a noun.

Which of the following is the analysis in the given passage?

  • “Your father and I are not going to simply replace your phone for you in order for you to have the same style of phone that your friends have. Once your current phone no longer works, we will talk about replacing it with a smartphone.”

  • “Mom, I feel that I deserve to have a smartphone. I have had this flip phone for three years and I have not lost or broken it. As you can see, it still looks like new.”

  • “Daughter, you do not need a new cell phone because your current cell phone still works. As you have stated, you have not broken your phone so it does not need replaced.”

  • “Once your current phone no longer works, we will talk about replacing it with a smartphone.”

Correct answer: “Your father and I are not going to simply replace your phone for you in order for you to have the same style of phone that your friends have. Once your current phone no longer works, we will talk about replacing it with a smartphone.”

The analysis in the given passage is: “Your father and I are not going to simply replace your phone for you in order for you to have the same style of phone that your friends have. Once your current phone no longer works, we will talk about replacing it with a smartphone.” A passage’s analysis is used to explain how the evidence is supporting the claim and it wraps up the text. It demonstrates the speaker has contemplated and analyzed the situation, and reached a conclusion (you just want to be like your friends).

The statement: “Mom, I feel that I deserve to have a smartphone. I have had this flip phone for three years and I have not lost or broken it. As you can see, it still looks like new” is the claim, reason, and evidence. A claim is the primary argument. The reason supports the claim. Evidence shows what the claim looks like by using facts, details, or examples. The statement: “Daughter, you do not need a new cell phone because your current cell phone still works. As you have stated, you have not broken your phone so it does not need replaced” is the counterclaim, reason, and evidence. A counterclaim is the opposition’s argument (claim) against the author’s claim. The statement: “Once your current phone no longer works, we will talk about replacing it with a smartphone” is only a portion of the analysis, not the complete analysis.

A 0.2-kg button is spun in a circle on a 1.0-m string. If the string breaks at 10 N of tension, how fast must the button be moving?

  • 7.1 m/sec

  • 50 m/sec

  • 2 m/sec

  • 3.5 m/sec

Correct answer: 7.1 m/sec

This problem can be solved by converting the centripetal force equation (Fc = mv2/r) to solve for velocity (v = √(Fcr / m). The centripetal force (10 N) is supplied by the tension in the string. The radius of the circle is 1.0 m, and the mass of the button is 0.2 kg.

v = √((10 N)(1.0m) / 0.2kg)

v = 7.1 m/sec

Newtons (N) are also expressed in kg – m/sec2

Newton's First Law states that a body at rest tends to remain at ______, while a body in motion tends to remain in ______.

  • rest, motion

  • motion, rest

  • friction, rest

  • motion, friction

Correct answer: rest, motion

Newton's First Law states that a body at rest tends to remain at rest, while a body in motion tends to remain in motion.

Newton's Laws of Motion:

First law: The velocity of a body remains constant unless the body is acted upon by an external force.

Second law: The acceleration (a) of a body is parallel and directly proportional to the net force (F) and inversely proportional to the mass m, i.e., F = ma.

Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear.

Which of the following options best punctuates the given sentence?

  • Yuck! Get the spider off of me!

  • Yuck, get the spider off of me?

  • Yuck, get the spider off of me …

  • Yuck, get the spider off of me.

Correct answer: Yuck! Get the spider off of me!

The statement being made is most likely expressing a strong feeling, as the individual most likely doesn’t want the spider on him or her. An exclamation point should be used when expressing a strong feeling.

A question mark should not be used because the sentence is not asking a question. A period could be used to complete the sentence; however, since the sentence is demonstrating a strong feeling an exclamation point would be best. An ellipsis could be used for this sentence; however, the sentence doesn’t indicate that words are omitted or that a pause is needed.
