This week, Mr. Alvarez's sales receipts totaled $32,199.

How much more did Mr. Alvarez's sales receipts total this week than last weekA. $ 3,363B. $ 6,763C. $13,363D. $16,763Item Status: Biased.Comments and revision(s) (if necessary):The item is a problem relating to the sales figures mentioning the word salesman. Use of this word indicates a gender bias as it is an occupation that can be done by both genders. Besides, it can give opinions regarding the performance of people with a similar name. The problem can be stated without the use of a name or the type of store.

Eg: A salesperson's receipts totaled to $25436, last week and $32199 this week. What is the expected increase in receipts this week2. Students in the Physics & Astronomy Club are buying telescopes to watch the upcoming lunar eclipse. They found comparable telescopes, at the following prices, each either on sale or with a special pricing offer:Name of StudentOriginal PriceSpecial OfferRussell$ 600.0010% offLouis$ 450.0015% offAmy$ 550.00$50 rebateStan$ 500.005% off original price and $35 rebateBernie$ 480.

00$40 rebateMike$ 500.0012% offAccording to the table, which student saved the mostA. RussellB. LouisC. AmyD. MikeItem Status: Contains BiasComments and revision(s) (if necessary):The item contains difficult vocabulary such as physics and lunar eclipse that have no bearing on the question.The item stem is also wordy and unclear. Buying a telescope for watching a lunar eclipse has little to do with savings. It is not necessary to have information of students not found in the choices. Naming the object to be purchased is also not necessary and makes the problem more complicated to understand.

The item also contains gender bias as the number of male student names are more than female student names. If we also look into the choices, we can note that there is an imbalance. Three of the choices have % off and only 1 represents a rebate. It is proper to have equal representation. The item can be rephrased as: A certain item was sold at different prices at a store.ItemOriginal PriceSpecial OfferA$ 600.0010% offB$ 450.0015% offC$ 550.00$50 rebateD$ 480.00$40 rebateWhich of the above gives the maximum saving on the pricea) Bb) Cc) Dd) A3.

The Johnsons are considering hiring an au pair for their child. One very good applicant requests a stipend of $800 per month and health insurance, which will cost them an additional $250 per month.

Comparable daycare would cost them $300 per week. What is the cost difference between the au pair and daycare for a full year a. The au pair will cost $3,000 more. b. Daycare will cost $3,000 more. c. Daycare will cost $1,440 more. d. There is no difference in cost.Item Status: Contains biasComments and revision(s) (if necessary):The item contains a language bias. Use of the term au pair could be confusing vocabulary for certain students. The item can be framed using personal child care and day care service.

The answer also reflects that personal baby care is cheaper compared to day care resulting in elitism bias. Mentioning the word good in the item also gives readers and opinion that good applicants are cheaper compared to day care services. The item can be rephrased as: The cost of personal baby care service per month is $ 800 and health insurance equivalent to $250. Day care for a baby costs $300 per week. What is the cost difference between the two services for a yeara) Personal baby care will cost $3000 more b) Day care will cost $ 3000 morec) Daycare will cost $ 1440 more d) There is no difference in cost.5.

Slavery is an emotionally charged issue, and including a question about it out of context offers no benefits and might, in fact, incur costs.The question could as easily be about the perimeter of the house of Hiram Revels. The item can be rephrased as:Archeologists discovered a home believed to be occupied in the mid 19th century. The home was constructed in the 1840's. Use your ruler and legend to find the perimeter in feet.6. Loretta's family lives on an Indian reservation in New Mexico.

How much money did they makeA. $ 75B. $ 120A. $ 150B. $ 160Item Status: Contains biasComments and revision(s) (if necessary): This question presents offensive stereotyping of Indians by implying they all live on reservations. It also describes the family income as meager: a demeaning term. The item can be rephrased as: A family sells fry bread at the state fair. The bread sells for $1.50 per portion.

The item also contains age bias by saying that Christmas decorations are generally given to the old as they are unable to make the same.

It also contains elitism bias as giving is a form of donation which clearly shows that the aged are weak have to be donated with. The item can be rephrased as: Two people A and B made decorations for the festive season. The table below shows how many decorations they made each day for one week. How many decorations did A and B make in all during this week 9. A cat is trapped on the second floor of a burning house. To rescue the cat, the firefighter gets a ladder from his fire truck.

It needs to be more concise. There is no requirement to mention purpose of rescue, objects around the house and the 'firefighter' term because it has no direct bearing in the question.

There was also a gender bias as the term 'his' was associated with the firefighter. The item can be rephrased as:To conduct a rescue operation, a person needed to use a ladder long enough to have one end reach 24 feet above ground while the other end braced 10 feet from the wall. How long is the needed ladderGraphic from http://www.palouse.net/mcctwigg/othwheel.htm10.
