The text the question is referring to is the following:
(1)A robot is a machine that is able to perform a variety of tasks through the use of a computer. (2)This computer is programmed to control movements of the robot's legs, arms, and other appendages by calculations of the various angles through which the robot's joints move. (3)Robots are made ideal for assembly line factory work by these repetitive movements. (4)Some robots are able to handle small parts that fit into small places. (5)Other robots are able to operate tools, such as paint sprayers.1
(6)Robots may even be developed with a sense of vision through the use of TV cameras as eyes. (7)Scanning images and calculating sizes and positions of surroundings will help robots to perform many actions in the way that humans do. (8) I want a robot to do my homework.
Answer:
D) sentence 8
Explanation:
The overall text has a formal and impersonal style, free of idioms, contractions, and subjective opinions, and its syntax (the way in which words are combined to form proper sentences) follows the formula of subject + verb (mainly the verb “to be”). But sentence 8 does not follow this pattern. This sentence seems out of place: It expresses a desire (it is personal), it is not descriptive, uses informal words, and follows the syntax subject + verb + object.
