Moby dic I can't write the other word but you get it
the first paragraph is talking about people should use public transport more to reduce the production of pollution to help decrease high amount of pollution, in towns and cities, carbon dioxide production can affect weather, and the environments it also decreases traffic and helps people
the second paragraph talks about how public transport isn't it a valid option for people who travel out of cities to in small towns, they speak how they need energy efficient cars to reduce the production of pollution and gas
The correct option is D) “Both A & B are incorrect.” Both sentences are incorrect because of the use of the phrasal verb “stand up”. The meaning of the phrasal verb is to make yourself into an upright position and a bike cannot “stand up”. The correct verb would be “stand”, which means to take or maintain a specified position.
The rest of the options are incorrect since the phrasal verb "To stand up" is on both sentences.
To my mind, the answer ( B ) is the inappropriate sentence. In a formal writing informal tone must be avoided as well as colloquial expressions.
Pretty sure it's the First and Third sentence.
