Activity 12, page 132 Although a (article) real airplane is controlled from within the cockpit while a model plane is controlled with a remote control, to fly / flying (word form) each of our planes requires a similar technique. Consequently, because I know how to fly my real plane, I was easily able to fly the model plane. Both have (subject-verb agreement) a throttle that controls the speed of the plane. Both use (verb tense) a rudder on the vertical tail fin that steers the plane left and right while in the air. Also, both use ailerons on the wings that bank the plane to the left or to the right. Both use wheels to taxi to the runway on the ground. In fact, in a real plane, the same foot pedals steer (verb tense) the plane left and right while in the air and guide the plane left and right while on the ground. Similarly, the (article) same left-right motion on the remote control moves (passive voice) both the rudder and the wheels.

The confidence that a person gains from feeling healthy and in shape improves his or her social and business relationships.

For example, many people make (subject- verb agreement) friends at the local (word form) gym.

- Training for a triathlon can be [correct] difficult, exciting, and rewarding all at the same time. To prepare for a triathlon, there is [are] three disciplines that one must master: swimming, biking, and running. While all three require [correct] endurance, each of the three sports require [requires] the development of unique skills.
Activity 2, page 216
- In most triathlons, the first event to compete in is the swim. Depending on the type of triathlon, the distance can be anywhere from 400 meters to 2.4 miles. Triathletes train for the swim portion of their race and do everything that they can to improve their efficiency in the water. In other words, they work on their form so that they move as fast as possible while expending as little energy as possible. While most triathletes excel at either the bike or the run, few are experts at the swim. For this reason, most triathletes take the approach of just getting through the swim and then attempt to make up time in either the bike or the run.
Activity 3, page 217
- The second event in a triathlon is the bike. Depending on the type of triathlon, the bike distance can be anywhere from 10 to 112 miles. Beginners average around 15 miles per hour while advanced riders keep up a blistering pace of more than 25 miles per hour. When training for this event, most triathletes ride a minimum of several hours a week in order to increase their endurance. In fact , some will ride as much as 20 hours per week. Showing their determination, some riders will also incorporate cross training into their routine, such as skiing or rowing. Because the bike is the longest of the three events, many triathletes focus most of their attention on this event.
Activity 4, page 217

- While many people recognize smoking as a leading cause of lung cancer, few realize that it is also one of the main causes of heart disease. In fact, most smoking-related deaths are the result of the effect that smoking has on the heart and blood vessels. Specifically, smoking increases blood pressure, tightens arteries, and causes irregular heartbeats, all of which put added stress on the heart. Various chemicals in cigarette smoke also cause the buildup of fatty plaque in the arteries, which can cause a person to have a heart attack. One can of course avoid all of these risk factors simply by choosing not to smoke.
