Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Although most universities in the United States are on a semester system, which offers classes in the fall and spring, some schools observe a quarter system comprised of fall, winter, spring, and summer quarters. The academic year, September to June, is divided into three quarters of eleven weeks each beginning in September, January, and March: the summer quarter, June to August, is composed of shorter sessions of varied lengths.

There are several advantages and disadvantages to the quarter system. On the plus side, students who wish to complete their degrees in less than the customary four years may take advantage of the opportunity to study year round by enrolling in all four quarters. In addition, although most students begin their programs in the fall quarter, they may enter at the beginning of any other quarters. Finally, since the physical facilities are kept in operation year round, the resources are used effectively to serve the greatest number of students. But there are several disadvantages as well. Many faculties complain that the eleven- week term is simply not enough for them to cover the material required by most college courses. Students also find it difficult to complete the assignments in such a short period of time.

In order to combine the advantages of the quarter system with those of the semester system some colleges and universities have instituted a three-term trimester system. In fourteen weeks, faculty and students have more time to cover material and finish course requirements, but the additional term provides options for admission during the year and accelerates the degree programs for those students who wish to graduate early.

Which of the following characteristics does NOT apply to trimesters?

A. They are long enough to cover the course material.

B. They last eleven weeks.

C. They provide more options for admission.

D. They allow students to graduate early.

The concept of urban agriculture may conjure up images of rooftop, backyard or community gardens scattered among downtown city streets and surrounding neighborhoods. But in the Seattle area, and within and beyond the Puget Sound region, it means a great deal more. “Urban agriculture doesn’t necessarily equate to
production that occurs only in a metropolitan urban area, “says Jason Niebler, who directs the Sustainable

Agriculture Education (SAgE) Initiative at Seattle Central Community College. “It means we are providing for growing population food needs from surrounding rural landscapes, as well as from the core urban landscape.”

Picture a series of concentric circles, with an urban core that produces some food at varying capacities, surrounded by a series of outlying rings of small farms that become increasingly more rural with distance. The hope is that such land use planning, from the inner core to the outer rings, will encourage local ecologically sound sustainable food production. This, in turn, will create local jobs and decrease reliance on distant food
products that originate from petroleum-intensive large scale farms.

That’s the idea behind SAgE, believed to be the nation’s first metropolitan-based community college sustainable agriculture program that emphasizes farming practices across diverse landscape types from urban centers to surrounding rural environs. “It’s small scale agriculture with an urban focus,” Niebler says. “Any urban population, large or small, can practice sustainable agriculture, improve food security and protect the
environment, which ultimately results in resilient food systems and communities.”

SAgE is a part of National Science Foundation’s Advanced Technological Education (ATE) Program, which is providing the project with $157,375 over two years. ATE’s goal is to support projects that strengthen the skills of technicians who work in industries regarded as vital to the national’s prosperity and security. The support largely goes to community colleges that work in partnership with universities, secondary schools,
businesses and industries, as well as government agencies, which design and implement model workforce initiatives.

The SAgE project focuses on the environmental, socioeconomic, political and cultural issues related to sustainable food systems, within Puget Sound watersheds through student and community education and research, and technological innovation. The curriculum offers courses that cover such issues as agricultural ecology, urban food systems, food politics and ethics, soil science, sustainable food production and technology,
the integration of food and forests, and career opportunities.

“We’ve created a curriculum that is fundamental in nature, addressing the principles of sustainable agriculture and what a food system is – how it functions both locally and globally,” Niebler says. “These courses are challenging, robust and inspirational. One of the really wonderful things about them is that we offer service learning opportunities, where students volunteer a portion of their time to working with local partner
organizations. They can do a research project, or a service learning option. The ideal would be to prompt students into careers that involve sustainable practices in an urban agriculture setting.”
