Answer to Question 1

Correct Answer: 3
Rationale 1: Protozoans are not easily treated.
Rationale 2: Protozoans can be passed through vectors.
Rationale 3: The protozoans go through maturation stages in the host.
Rationale 4: Protozoans have long lives.
Global Rationale: The protozoans go through maturation stages in the host. They have long lives and can be passed by vectors. Infections with protozoans are not easily treated.

Answer to Question 2

Correct Answer: 2
Rationale 1: A worm is a helminth.
Rationale 2: The growing stage of a protozoan is a trophozoite.
Rationale 3: A vector is a transmitter of organisms.
Rationale 4: Cysts are developed to protect an organism and are not part of the growing stage.
Global Rationale: The active, growing stage during which the organism feeds, often at the expense of its host, is the trophozoite stage. A worm is a helminth. A vector is a transmitter of organisms. Cysts are developed to protect an organism and are not part of the growing stage.
