Each bolt weighs 100 grams, and there are 90 in a box. It also has 100 more bolts inside, each weighing 150 grams. What is the weight of the empty box if the complete package weighs 35,500 grams?

Correct! Wrong!

Explanation:
The total weight of the bolts can be calculated as follows:

Weight of 90 bolts (100 grams each) = 90 x 100 = 9,000 grams
Weight of 100 bolts (150 grams each) = 100 x 150 = 15,000 grams
Total weight of bolts = 9,000 + 15,000 = 24,000 grams

To find the weight of the empty box, we can subtract the weight of the bolts from the total weight of the box:

Weight of empty box = Total weight of box - Total weight of bolts
Weight of empty box = 35,500 - 24,000 = 11,500 grams

Therefore, the weight of the empty box is 11,500 grams.

Decide on the grammatically soundest sentence.

Correct! Wrong!

Explanation:
The sentence "We are taking the following: two suitcases, a purse, a laptop, a camera, and one coat." is most grammatically correct.

Government representatives at the IRS attempted to establish a priority workplace family. In other words, they desired a more hospitable IRS. Congressman Watson told the legislature, "We should implement a national family policy that includes legislation forcing employers to give paid parental leave and establish government-sponsored daycare.

Which of the following best clarifies the passage?

Correct! Wrong!

Explanation:
The statement "Any national family policy that is adopted would include legislation requiring employers to provide paid parental leave and establish government-sponsored daycare" best clarifies the passage.

Jason Varner must finish his report by 1:00 p.m. A glossary of concepts and five sections make up this report. Twelve different terms related to the terminology used in the information should be included in the glossary. Jason must have his employer assess their work once it is finished. How many grammatical mistakes can you find in the previous sentence?

Correct! Wrong!

Explanation:
There are seven grammatical errors in the above paragraph:

1. "pm" should be "PM" since it is an abbreviation for "post meridiem."
2. "Jason Vanert" should be "Jason Vanert's" since it is possessive.
3. "five sections, and a glossary of terms" should be "five sections and a glossary of terms" since there should not be a comma before "and" in a list.
4. "term" should be plural in "twelve different terms."
5. "that relates to the use of the term" should be "that relates to the terms used" since "terms" is plural and "used" is the correct past participle of the verb.
6. "their" should be "his" since "Jason" is a singular male noun.
7. "boss" should be "boss's" since it is possessive.

"Which order is incorrect?" Key: 1 7 6 9 2 4 8 3 J O E L F A S H, the code."

Correct! Wrong!

Explanation:
The given key and code can be combined as follows:
1 7 6 9 2 4 8 3
J O E L F A S H

To create the required sequence, we must match the code's letters with their corresponding numbers in the key. The resulting sequence would be:
1 6 9 2 3
J E L F H

Therefore, the correct sequence is 16923-JELFH.

As we can see, the original key and code sequence given in the question are already in the correct order, so none of the lines is out of order.
