(1) Seaweed-based fuel could one day power your car. (2) It is more than just an ingredient in a
purifying face mask or a sushi roll. (3) According to new research, seaweed has the potential to
become an advanced biofuel known as biobutanol. #$%^&
(4) In the past, U.S. scientists have looked to the possibility of algae-based biofuels, but most
of these explorations have shied away from kelp and seaweed. (5) One reason why seaweed
may not have taken off as a potential fuel source
is the fact that it's not a major part of American culture. (6) In contrast, in Asian countries such
as Japan, there has been a long history of seaweed in the cuisine. (7) Japanese researchers are
much more familiar with it and have spent decades studying its potential uses.
(8) A second reason for the U.S. avoidance of seaweed-
based biofuel is the country's lack of experience with seaweed farming. (9) The U.S. is no
stranger to seaweed harvesting - (ANSWERS)Choice (C) is correct. The new sentence must be
a logical and grammatical combination of the existing sentences, which indicate that
"Seaweed-based fuel could one day power your car" and that "It" (presumably, seaweed) "is
more than just an ingredient in a purifying face mask or a sushi roll." Only (C) properly orders
the two claims, first expressing that "Seaweed is more than just an ingredient . . ." and then,
following a correct use of a semicolon to join two related independent clauses, narrowing the
focus to "seaweed-based fuel." The other choices introduce errors: choice (A) creates a comma
splice (two independent clauses joined by only a comma), choice (B) provides an illogical
cause-effect statement, and choice (D) contains a vague pronoun ("it").

based biofuel is the country's lack of experience with seaweed farming. (9) The U.S. is no
stranger to seaweed harvesting. - (ANSWERS)Choice (B) is correct. The new sentence, "There
are a number of possible reasons for this," needs to fit logically and grammatically between two
existing sentences. Sentence 4 states that American scientists have "shied away from," or
ignored, kelp and seaweed as possible biofuels. Sentence 5 notes "One reason why seaweed
may not have taken off as a fuel source." Later in the passage, sentence 8 provides "A second
reason for the U.S. avoidance of seaweed-based biofuel." The new sentence fits logically and
grammatically between sentences 4 and 5 because it introduces the reasons for "this"
(American scientists' neglect of kelp and seaweed as potential fuel sources)— reasons that are
provided in the following sentences. On the contrary, if choices (A), (C), or (D) were chosen as
the answer, "this" would refer to other things for which no reasons are given.

(8) A second reason for the U.S. avoidance of seaweed-
based biofuel is the country's lack of experience with seaweed farming. (9) The U.S. is no
stranger to seaweed harvesting. - (ANSWERS)Choice (A) is correct. The inserted word or phrase
must properly link sentence 7 with the sentences that come before it in the passage. Sentences
5 and 6 suggest that unlike the U.S., where seaweed has not been considered a potential fuel
source because U.S. scientists are not familiar with it, Japan has "a long history of seaweed in
the cuisine." Sentence 7 states that "Japanese researchers are much more familiar with it and
have spent decades studying its potential uses." Only the phrase "As a result" properly links
sentence 7 with what has come before: in the context of the passage, Japanese scientists'
familiarity with seaweed is clearly a result of its history as a food in their culture. Choices (B)
and (C) suggest a contrast between sentences 6 and 7 that does not exist, and choice (D)
suggests that sentence 7 simply adds more information to sentence 6 rather than showing the
proper cause-effect relationship.

fit logically and grammatically between sentence 9 ("The U.S. is no stranger to seaweed
harvesting") and sentence 10 ("However, for the biobutanol project to be environmentally
sustainable, seaweed cannot be harvested; it must be farmed"). The only sentence that
provides a direct link back to sentence 9 and forward to sentence 10 is choice (C): "Maine
Seaweed Co., for instance, harvests the seaweed naturally available along the U.S. coast." This
sentence provides the example of Maine Seaweed, a seaweed-harvesting company, to support
the claim in sentence 9 that the U.S. is familiar with seaweed harvesting. And sentence 10
seems to refer back to the work of Maine Seaweed in stating that "However . . . seaweed cannot
