TOEFL Practice Test 9

Question 1

Choose the correct answerApple Computer has unveiled its new desktop computer design, _____ all disk drives and processors into a flat display less than two inches thick

Accepted Answer

Which integrates

Answer

The word 'integrates' best conveys the idea of combining different components into a unified, functional whole, which is precisely what a new computer design that incorporates drives and processors into a display achieves. It suggests a seamless and cohesive merging of elements. 'Includes' or 'contains' are too general, while 'enclosing' implies merely surrounding, not necessarily making them a part of the display itself.

Question 2

Select the right response. Because ____ are lousy behavior observers, their children's inappropriate behavior becomes out of control.

Accepted Answer

Parents

Answer

The sentence requires a simple subject for the verb 'are' within the dependent clause 'Because ____ are lousy behavior observers.' 'Parents' functions as a straightforward plural noun, correctly completing the clause and making it grammatically sound. The other options introduce unnecessary words or structures that would create grammatical errors or alter the intended meaning of the sentence.

Question 3

There are 4 underlined sections in the text below. Select the one which is wrong.The Eiffel Tower was built the International Exhibition of Paris of 1889commemorating the centenary of the French Revolution.

Accepted Answer

Was built

Answer

The phrase 'was built' is grammatically incomplete in this context. To correctly express the purpose or occasion for which the Eiffel Tower was constructed, a preposition like 'for' is needed. The sentence should read 'The Eiffel Tower was built for the International Exhibition...' to properly link the verb to the event, indicating its intended purpose.

Question 4

Choose the correct answerThe number of girls in school and women in parliaments has risen, and their overall access to contraception has improved in the past decade, _____ new report.

Accepted Answer

According to a

Answer

The phrase 'according to' is the correct and idiomatic expression used to attribute information or a statement to a specific source, such as a report. It means 'as stated by' or 'as reported by,' and is essential for properly citing the origin of the information presented in the sentence. The other options are grammatically incorrect or do not fit the standard usage for attribution.

Question 5

Choose the correct answerAstronomers on _____ announced the discovery of a new -- and possibly abundant -- class of planets that has more in common with Earth than the uninhabitable gas giants previously discovered.

Accepted Answer

Tuesday

Answer

The preposition 'on' is correctly used when referring to a specific day of the week, indicating when an event took place. Therefore, 'on Tuesday' is the only grammatically appropriate option to specify the timing of the astronomers' announcement. While astronomers work in labs or for organizations like NASA, 'on' typically precedes a day or date, not a location or organization in this context.
