Before we get down to business, let us remember that when we compare a person with another person, the comparison is straight and does not require an action verb. Such comparisons involve the use of the basic verb ‘be’ or its derivatives such as ‘is, am, are etc;’
e.g: She is obese like her mother; the verb
‘is’ is the third person singular form of
‘be’ and the sentence compares she with her mother.
On the contrary, when we compare an action, as indicated by a working verb of the first arm of the comparison, then the second arm also will have to be represented by an action verb in order to complete the comparison parallelly.
E.G: He sings like his brother; here the comparison is between the way he sings with the way his brother sings. So we have to add the verb sings or an equivalent one to the way of his brother . But ‘
like his brother sings’ is grammatically wrong. So we have to say that he sings as his brother does. (does means sings)
In the light of the above norms, let us look at each choice.
Nobody knows GMAT like we do ---- w
rong…. Like we do is a clause and can not follow ‘like’ Nobody knows GMAT like us ……
compares GMAT with us --- wrongNobody knows GMAT like we
….. compares GMAT with we --- wrongNobody knows GMAT as we do ….
Knows is action verb; hence we need an action verb for 'we' also. The correct choice. Nobody knows GMAT as we ……..
compares GMAT with we and the sentence is incomplete Nobody knows GMAT as us ………
compares GMAT with us --- wrongNobody knows GMAT as we are ……..
Irrelevant compares knowing with our being. Nobody knows the baby better than the mother and Johnson & Johnson ……
the second arm needs an appropriate verb to match the verb ‘knows’ in the first part. Because this is a comparison about knowledge between two sets. Nobody knows the baby better than the mother and Johnson & Johnson know….
Grammatically correct but somewhat inferior to another choice because of the redundancy of ‘know’
Nobody knows the baby better than he knows the mother and Johnson & Johnson …
wrong The sentence compares baby with the mother and a company … Nobody knows the baby better than he does the mother and Johnson & Johnson
wrong comparison … wrong; comparing baby with the mother and a company
Nobody knows the baby better than ‘
does' the mother and Johnson & Johnson’ …
SV -agreement problem Nobody knows the baby better than do the mother and Johnson & Johnson…….
correct choice with action verbs on both sides. The verb ‘do’ is better than ‘know’ because of avoiding redundancy He is bold like his brother
….. perfect He is bold as his brother
…… incompleteHe is bold like his brother is ….
Grammatically wrongHe sings like his brother …..
Needs action verb for second arm He sings like his brother does …
wrong … like is followed by a clause.He sings as his brother does …
.. perfectHe is tall like his brother is but jumps higher than his brother jumps………
first portion compares person with person and so no need for the verb ‘js’for the brother; The second part compares an action of jumping. So you require a verb for the brother. Jumps is however repetitive. Not a good choice. He is tall like his brother but jumps higher than his brother…
wrong; we do need a verb for his brother’s jumping in the second part. Otherwise jumping gets compared with his brother.He is tall like ‘his brother is’ but jumps higher than does his brother …l
ike his brother is wrong He is tall like his brother but jumps higher than does his brother …
perfect choice; no action verb in the first part. Action verb ‘does’ in the second arm is better than ‘jumps’.He is tall like ‘
his brother is’ but jumps higher than his brother….
’like his brother is’ wrong i would like people to add more on this.
