Problem: The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychaetes. Annelids are considered members of the Lophotrochozoa, a "super-phylum" of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans.

The basic annelid form consists of multiple segments. Each segment has the same sets of organs and, in most polychaetes, has a pair of parapodia that many species use for locomotion. Septa separate the segments of many species, but are poorly defined or absent in others, and Echiura and Sipuncula show no obvious signs of segmentation. In species with well-developed septa, the blood circulates entirely within blood vessels, and the vessels in segments near the front ends of these species are often built up with muscles that act as hearts. The septa of such species also enable them to change the shapes of individual segments, which facilitates movement by peristalsis ("ripples" that pass along the body) or by undulations that improve the effectiveness of the parapodia. In species with incomplete septa or none, the blood circulates through the main body cavity without any kind of pump, and there is a wide range of locomotory techniques some burrowing species turn their pharynges inside out to drag themselves through the sediment.

Problem: Jason lay in his bed after a night of no sleep. He was too excited for today. There was a football game that he was going to play with his friends. It would be him, Jack, James, and John competing with David, Ruth, Parsons, and Mike. David, Rush, Parsons, and Mike were much bigger than them, and were big bullies at school. When Jason got up, he had the choice to eat cereal, candy, chocolate milk, or pizza. He chose to eat cereal because he thought that eating something good for you would make him play better. They were going to play at the school, but the school was closed. They then went to the park, and got their teams set up. Jason's team got the ball first and they scored! David's team got the ball next, but they also scored. Unfortunately, it started raining. Everyone was getting wet, and people were starting to get angry. A fight soon broke out, and they all started fighting with each other. Eventually, Jason yelled for everyone to stop. They all stopped and chose to eat pizza together and forgive each other. Jason then went home bruised and dirty, and his parents grounded him for getting into a fight.

Problem: Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam approximately north of London. At the United Kingdom Census 2011, its population was 123,867, including 24,488 students.

There is archaeological evidence of settlement in the area in the Bronze Age and in Roman Britain; under Viking rule, Cambridge became an important trading centre. The first town charters were granted in the 12th century, although city status was not conferred until 1951.

The University of Cambridge, founded in 1209, is one of the top five universities in the world. The university includes the Cavendish Laboratory, King's College Chapel, and the Cambridge University Library. The city's skyline is dominated by the last two buildings, along with the spire of the Our Lady and the English Martyrs Church, the chimney of Addenbrooke's Hospital and St John's College Chapel tower. Anglia Ruskin University, evolved from the Cambridge School of Art and the Cambridgeshire College of Arts and Technology, also has its main campus in the city.

Cambridge is at the heart of the high-technology Silicon Fen with industries such as software and bioscience and many start-up companies born out of the university. More than 40% of the workforce has a higher education qualification, more than twice the national average. The Cambridge Biomedical Campus, one of the largest biomedical research clusters in the world, is soon to be home to AstraZeneca, a hotel and the relocated Papworth Hospital.
