The following text is from a poem.
The kettle sings its morning tune, The clock ticks in the hall; I set two cups upon the cloth, Without a thought at all. I fill the one and leave the one Beside your empty chair, And though I know you will not come, I keep it waiting there.
Which choice best states the main purpose of the text?
AA. To describe the objects in the speaker’s kitchen in precise detail
BB. To explain why the speaker no longer enjoys drinking tea in the morning
CC. To convey the speaker’s sense of loss through a familiar daily routine
DD. To contrast the speaker’s lively mornings with the quiet of the evenings
Ver respuesta y explicación
Respuesta correcta: C. To convey the speaker’s sense of loss through a familiar daily routine
Explicación
Out of long habit (“Without a thought at all”), the speaker still sets out two cups but fills only one, leaving the other beside “your empty chair” for someone who “will not come.” The ordinary morning routine is the means by which the poem conveys the speaker’s sense of loss.
The kettle, clock, and cups are mentioned, but only briefly and to show the routine, not to describe the kitchen in detail. Nothing suggests that the speaker dislikes tea. The poem describes only the morning; there is no contrast with the evening.

Dung beetles roll balls of dung away from crowded dung piles in straight lines, which keeps rival beetles from stealing their prize. Remarkably, they can hold a straight course even on moonless nights. In a series of experiments, biologist Marie Dacke and her colleagues found that the beetles steer by the faint band of light from the Milky Way.
Which choice best describes the function of the underlined sentence in the text as a whole?
AA. It explains why dung beetles move their dung away from crowded piles at all.
BB. It contrasts dung beetles with other insects that are active at night.
CC. It presents a surprising ability that the final sentence then explains.
DD. It casts doubt on the results of the experiments described in the final sentence.
Ver respuesta y explicación
Respuesta correcta: C. It presents a surprising ability that the final sentence then explains.
Explicación
The underlined sentence, marked by “Remarkably,” points out something surprising: the beetles keep a straight course even when there is no moon. The final sentence then explains how they do it—by steering with the light of the Milky Way.
The reason for rolling dung away is given in the first sentence, not the underlined one. No other insects are mentioned, and the underlined sentence does not question the experiments; it sets up their finding.

The following text is from a short story set in the nineteenth century. A young clerk has just received a letter offering him a position in a distant city.
Thomas read the letter twice, then folded it carefully and placed it inside his coat. All afternoon he copied figures into the ledger as if nothing had changed, and when Mr. Hale passed his desk and asked whether the morning post had brought anything of interest, Thomas said that it had not. Only on the walk home, as the lamps along the river were lit one by one, did he take the letter out again and stand reading it until the light was gone.
Which choice best describes the function of the underlined portion in the text as a whole?
AA. It reveals that Thomas has already decided to turn down the position.
BB. It shows that Thomas suspects Mr. Hale of having read his private letter earlier in the day without his permission.
CC. It indicates that Thomas has misunderstood what the letter offers him.
DD. It suggests that Thomas is not yet ready to share or act on the news the letter contains.
Ver respuesta y explicación
Respuesta correcta: D. It suggests that Thomas is not yet ready to share or act on the news the letter contains.
Explicación
Thomas hides the letter, works “as if nothing had changed,” and tells Mr. Hale the post brought nothing of interest, yet later he stands rereading the letter until dark. His denial shows he is keeping the news to himself while he absorbs it, not yet ready to share it or act on it.
His long rereading of the letter suggests he is still considering the offer, not that he has refused it. Nothing indicates he suspects Mr. Hale of anything; Mr. Hale’s question is casual. The text says he read the letter twice and gives no sign he misunderstood it.
