TOEFL Complete the Words Practice #034 - How Camouflage Reduces Danger

Many small animals reduce danger by blending into the places where they live. This prot can de on color, pattern, and behavior, because an animal that clo res its surroundings is less likely to be not by a predator. Some species remain moti during the day and become ac only after darkness falls, while others change their position to match a dif background. Camouflage is especially eff when body markings break up a clear outline, making the animal's shape more difficult to reco from a distance. However, concealment is never perfect, so survival also depends on alert senses and a rapid response when danger approaches.

Answer Explanations Reveals the correct words

1.protection
‘Protection’ is a singular noun referring to the safety provided by blending into the environment. The determiner ‘This’ and the following modal construction ‘can depend’ show that a noun is needed as the sentence subject.
2.depend
‘Depend’ follows the modal verb ‘can,’ so it must appear in its base form. The phrase ‘depend on’ introduces the factors—color, pattern, and behavior—that determine how camouflage works.
3.closely
‘Closely’ is an adverb modifying ‘resembles.’ It explains the degree to which the animal looks like its surroundings, and the -ly ending signals its adverbial role.
4.resembles
‘Resembles’ is the present-tense verb for the singular subject ‘an animal that.’ It means looks similar to, which connects the animal’s appearance with its surroundings.
5.noticed
‘Noticed’ is the past participle in the passive construction ‘to be noticed.’ The context indicates that a predator is less likely to detect an animal that resembles its surroundings.
6.motionless
‘Motionless’ is an adjective following the linking verb ‘remain.’ The surrounding reference to staying still during the day clarifies its meaning, while the suffix -less means without movement.
7.active
‘Active’ is an adjective following ‘become.’ It contrasts with ‘motionless’ and describes the animals after darkness falls.
8.different
‘Different’ is an adjective modifying the singular noun ‘background.’ The sentence explains that some animals move so their appearance continues to match after the setting changes.
9.effective
‘Effective’ is an adjective following the linking verb ‘is’ and modified by ‘especially.’ The next clause explains the condition under which camouflage works particularly well.
10.recognize
‘Recognize’ is a base-form verb after the infinitive marker ‘to.’ The phrase ‘difficult to recognize’ means that broken body outlines make the animal’s shape harder to identify.
