Taking a Standardized Test
Test-Taking Tip: Mark Questions That Require
Guessing
When you take a test, read each question carefully. If you can answer the question, do so. If you
cannot answer a question, and think you will have to guess the answer, mark it. You can return to
it later.
Read the following question and answer choices.
A change in a population from high birth and death rates to low birth and death rates is known as
A. logistic growth.
B. demography.
C. limiting factors.
D. demographic transition.
Step 1 Answer the question if you can. If you know the answer, circle it. Move on to the next
question.
Step 2 If you do not know the answer, mark the question. For example, you may not
remember the meanings of all the terms listed in the question above. Lightly draw a star to the left
of the question. This will help you to quickly find the question again later. Then, move on to the
next question. Continue answering or marking questions until you reach the end of a test section.
Step 3 Return to marked questions. Eliminate answer choices you know are incorrect. For
example, you might remember that demography is the study of human populations. You know
that low birth rates probably do not mean growth. So, you can cross out A and B. Guess between
the remaining choices. The answer is D.
Self-Test
Practice what you have learned by answering the following questions. Read each question
and the answer choices. If you cannot answer the question, mark it and return to it later.
Answer all questions that require guessing last.
1. The maximum number of organisms of a particular species that can be supported by an
environment is called
A. carrying capacity.
B. logistic growth.
C. exponential growth.
D. population density.
2. A limiting factor that depends on population size is called a
A. density-dependent limiting factor.
B. density-independent limiting factor.
C. predator-prey relationship.
D. parasitic relationship.
