Question

A Fascinating Discovery

Read through the draft of an article about the discovery of a new species of titi monkey. Then go on to the suggestions for revision that follow. The numbered sentences in paragraph 1 are for use in answering questions.

(1} Titi monkeys are small fruit eating primates that live near water in dense forests. {2} They were first discovered in 1903. {3) This was in the Amazon Rainforest. {4) Since then, many different and various species have been found in that area. (5} The territory of a particular species is usually surrounded by rivers. {6) The titi does not swim, so an entire species live in a limited area. (7) Consequently, the number in each species is quite small. (8} In 2010, a group of Brazilian primatologists spotted a fascinating new monkey on the west bank of the Roosevelt River in the Amazon.

(2) However, especially in the early morning, like other titis, they engaged in frequent communal calling. Scientists think these calls help to create group cohesion. The calling is most intense in the rainy season, and their favorite trees are in fruit. It is probably a tactic to protect the fruit.

(3) They were finding that these monkeys are very much like their titi cousins in other parts of the Amazon. Their habitat is in a tropical forest, and they live primarally in the lower area called the undercanopy. The trees in this area are about fifty feet tall. The monkeys eat mostly the fruit of local trees, such as the Inga. Their fur is long and soft, and easily they jump from one tree branch to another. Their groups are small. Two to five monkeys live together. There is usually an adult pair also two or three offspring. Scientists have viewed adult titis carrying babies while searching for fruit. Because like other titis they do not swim they are confined by the rivers that surround their habitat. However, they differ from other titis in their bright coloring. In addition these new titis, to the strikingly colored tail also have orange-brown sideburns and bellies and a light gray forehead stripe.

(4) {C21}It was named Callicebus miltoni in honor of Dr. Milton Thiago de Mello. Dr. de Mello founded the primatology program at the University of Brasilia. He was also one of the creators of the Brazilian Primatology Society. The findings of the research group were published in a Brazilian zoological journal. The co-author Dr. Felipe Silva expressed his excitement about the discovery of the new species saying, "It is always thrilling to find something new in the Amazon, as it reminds us just how special this rainforest is and how lucky we are to have it on our doorstep." At the time of the discovery, thirty-one species of titi monkeys were recognized.

(5)This unusual monkey had coloring that did not match any known species. Intrigued by the monkey's orange tail, a group of specialists from several Brazilian primatology institutes formed a group to investigate. {C22 } The monkeys were running away whenever they were aware someone was watching. They were very shy. This made it difficult.

Which revision of the highlighted portion (However, especially in the early morning, like other titis, they engaged in frequent communal calling.) is most effective and grammatically correct?

Answers

No change
However, like other titis especially in the early morning, they engaged in frequent communal calling.
correct
However, like other titis, they engaged in frequent communal calling, especially in the early morning.
However, like other titis, they engaged, especially in the early morning, in frequent communal calling.

Explanation

The Correct Answer is: C. However, like other titis, they engaged in frequent communal calling, especially in the early morning.
This revision places the modifying phrase “especially in the early morning” at the end of the sentence, where it clearly and logically describes when the calling occurs. The structure flows smoothly, avoids awkward interruptions, and clearly communicates the comparison to other titis. It maintains grammatical correctness while improving clarity and readability within the paragraph.

Why the other options are incorrect:

A. No change
The original sentence is awkward because the modifying phrase “especially in the early morning” is placed too early. This disrupts the flow and makes the sentence feel cluttered. The multiple introductory elements also compete for attention, making the meaning less clear. Although grammatically acceptable, the structure is less effective and does not present information as smoothly as the corrected version.
B. However, like other titis especially in the early morning, they engaged in frequent communal calling.
This option places “especially in the early morning” directly after “other titis,” creating confusion. The sentence incorrectly suggests the other titis are especially in the early morning, rather than describing when the calling occurs. This misplacement leads to an illogical reading and weakens sentence clarity, making it an ineffective revision.
D. However, like other titis, they engaged, especially in the early morning, in frequent communal calling.
This version interrupts the verb phrase “engaged in frequent communal calling” by inserting “especially in the early morning” in the middle. Splitting the verb phrase makes the sentence choppy and less readable. The resulting structure is grammatically awkward and disrupts the logical flow of information, reducing overall clarity and effectiveness.
