Lightning quick tip of the day:
In Sentence Correction, the CORRECT option will NEVER place "in" (or any other preposition) after the words "like" or "unlike". "Like"/"Unlike" are ONLY followed by nouns (i.e., the names of people, animals, places, things, or ideas).
Example from OG Verbal Review Q 189:
With respect to most species of animals, they are evenly divided in right- or left-handedness, unlike humans.
(A) With respect to most species of animals, they are evenly divided in right- or left-handedness, unlike humans.
(B) With respect to right- or left-handedness, most species of animals are evenly divided, unlike in humans.
(C) Unlike humans, most species of animals are evenly divided with respect to right- or lefthandedness.
(D) Unlike in humans, most species of animals with respect to right- or left-handedness are evenly divided.
(E) Unlike humans, with respect to right- or lefthandedness, in most species of animals it is evenly divided.
The incorrectly used words are highlighted in red.
Concept: Like/Unlike X, Y:
Like her sister, she is an engineer.
Unlike humans, most species of animals…
X and Y must both ALWAYS be nouns (the names of people, animals, places, things, or ideas.
Pro tip: even if you can solve a practice question easily, ALWAYS ensure that you identify ALL the errors in the wrong options and, more importantly, ensure that you KNOW why they're incorrect! If in doubt, ask a reliable expert.
