Answer:
The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, such as whales, dolphins, and porpoises, are much more dependent on sound for communication and sensation than are land mammals, because other senses are of limited effectiveness in water. Sight is less effective for marine mammals because of the particulate way in which the ocean scatters light. Smell is also limited, as molecules diffuse more slowly in water than in air, which makes smelling less effective. However, the speed of sound is roughly four times greater in water than in the atmosphere at sea level. As sea mammals are so dependent on hearing to communicate and feed, environmentalists and cetologists are concerned that they are being harmed by the increased ambient noise in the world's oceans caused by ships, sonar and marine seismic surveys.[2]
Answer:
B. The cast will perform the play ten times between June 21st and July 1st.
Explanation:
The difference between active voice and passive voice is that active voice has the subject acting while the passive voice has the subject being acted upon.
In the original sentence, the subject is the performances. In answer B, the subject is the cast, who are doing the performing.
The gerund phrases are:
- "Being the accounts manager" (Subject)
- "blowing bubbles to his little sister" (Subjet Complement)
Gerund phrases begin with a gerund or -ing word, and include other modifiers and objects. They function as nouns, and can be the subject, subject complement or direct object of the sentence.
The rest of the alternatives are not gerund phrases because options one and three possess an infinitive verb ("to bring" and "to win"), and "Hiking for two hours" is a present participle clause.
