Unit 2 exercises

Identifying the definitional elements from the following passage

(Task 6)

The uncertainty associated with the energy obtained from other types of non-utility generators (NUGs), i.e., thermal and hydro, is relatively small compared to that associated with wind.

• the energy obtained from other types of non-utility generators (NUGs)

• i.e., thermal and hydro

• is relatively small

• compared to that associated with wind

Answer explanation

Identifying the definitional elements from the following passage

(Task 6)

Average raw scores on IQ tests have been rising for years (Flynn, 1984, 1987, 1999) by an estimated three IQ points per decade (Neisser, 1998). This rise, known as the Flynn effect, has received much attention, though its exact nature was recently questioned.

Answer explanation

Identifying the definitional elements from the following passage

(Task 6)

In addition to the examination of historical records, a study of the geologic record of past seismic activities, called paleo-seismology, can be used to evaluate the occurrence and size of earthquakes in the region. Geomorphic (surface landform) and trench studies may reveal the number of past seismic events, slip per event, and timing of the event at a specific fault.

(Task 10)

Pollution is a form of environmental contamination resulting from human activity. Some common forms of pollution are wastes from burning fossil fuels and sewage running into rivers. Even litter and excessive noise or light can be considered forms of pollution because of the impact they can have on the environment.

An acrylic plastic is a polymer that can take a high polish, is clear and transparent, and can be shaped while hot. Because of these and other characteristics, acrylic plastic is used in situations where glass is not suitable or desirable, for instance, in certain types of windshields.

A microscope is an optical instrument with which the apparent size of an object can be enhanced. A simple microscope consists of a double convex lens and a magnifying glass. A compound microscope, on the other hand, will contain more than one of each of these lenses, which are situated at the ends of a cylinder.
