You are a salesman for Dynacad Industries. Dynacad’s products are computer-aided design (CAD) systems that are sold into a variety of industrial companies. Though you had CAD experience in a previous job, you have been with Dynacad for 14 months and as of yet have not generated much business.

You are under pressure to produce when suddenly you are assigned a promising account that had been the responsibility of Jack Cutting. Jack had to retire suddenly because of severe health problems. The order that Jack was working on was for Dynacad’s largest and most expensive system, and would amount to a sizable deal for the company.

As you reviewed the customer’s needs and the model being proposed, you realized that this system is overly large and complex. However, the system you think would be a better fit for the customer costs far less than the larger, proposed system. What do you do?

10. Paper

Easy  
Verbal Reasoning Most effective summary Newspaper excerpts Public

Carefully read the following excerpt from an article on paper production:

With the recovery rate of used paper for recycling approaching 70 percent in the United States and Europe, and approaching 80 percent in Japan, to keep up with our demand for paper we need to continue using fresh fiber as well as recycled, according to the premise set forward in a new report by the World Business Council for Sustainable Development (WBCSD).

Detailing the reasons why fresh fiber combined with recycled is important for a single integrated wood fiber system, the report examines the “complementarity” of using both and discusses the functions of different types of fibers and the issues related to both recycling old fiber and sourcing fresh fiber. In 2012, 400 million tons of paper and paperboard were produced and consumed globally, which is double that in 1985, notes the report. As the population continues to expand and standards of living increase, this number is expected to climb by another 40 percent by 2028. While many would advocate for cutting down on paper use in the first place, in the face of global demand the most sustainable fiber may have to be the next best thing. But therein lies the rub: finding adequate quantities of said fiber will be the challenge of the global pulp and paper industry.

17. Economic Recession

Easy  
Verbal Reasoning Critical thinking New Public

Germany's economy avoided falling into recession during the final three months of last year. This means that it avoided two consecutive quarters of negative GDP growth, which is the definition of a recession. This was a small, but positive, surprise for all analysts who, after the July-to-September period that featured a 0.3% decline, predicted the continuation of this negative trend.

Reasons for slower growth last year include a slowdown in the global economy and a weaker car sector, with some German consumers less willing to buy new cars amid confusion over new emission standards.

Joe Johnson, senior financial analyst, told the BBC that US tariffs on EU car exports, which US President Donald Trump has threatened, could have a major impact on Germany. He thinks that, if this happens, Germany might fall into recession.

19. Sick Leave

Easy  
Verbal Reasoning Deductive reasoning Understanding rules Public

The company's sick leave policy says:

This company’s sick leave policy applies to all our employees who have been with our company for more than six months. Our employees can take sick leave only when they want to recover from a sudden illness, accident, or injury. They can use up to 10 days of sick leave for these purposes per calendar year.

Upon completion of each 12 month period of employment, employees will receive 3 additional days of sick leave for every completed 12 month period of working for the company. Unspent additional sick leave days cannot be transferred to the next 12 month period. For example, an employee who has worked for the company for 10 years would receive 30 additional days of sick leave, or 40 in total.

Keep in mind that employees who become sick should either use their sick days or work from home to avoid spreading illnesses.

Fill in the blanks, with numbers, for the cases below. Enter the number 0 for cases when an employee doesn't have the right to sick leave, according to the policy.

  • Emily, who has worked for us for almost half a year and still hasn't used any sick leave days, has the right to use up to __ sick leave days this year.
  • Faith, who just started her 3rd year of working for us and has not taken sick leave until now, had a car accident. She has the right to use up to __ days of sick leave to recover from her injuries.
  • Vanessa, who started to work for us a little over a year ago, took 2 days of sick leave last year. She was Faith's passenger in the car accident. Vanessa has the right to use up to __ days of sick leave to recover from her injuries.
  • Edith, who began working for us 8 months ago, has the right to use up to __ sick leave days for a volunteer adult care program at a local hospital that lasts the whole day.
  • If Gabrielle, who has worked for us for 20 months, and who took a 10-day sick leave immediately after her 6-month trial period had finished, gets ill tomorrow, she will have the right to use up to __  days of sick leave.
