Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 23 to 27. Fill in the appropriate word in question 33

Taking piano lessons and solving math puzzles on a computer significantly improve specific math skills of elementary schoolchildren, according to a new study. The results, (23) _______ were published in the journal Neurological Research, are the latest in a series that links musical training to the development of higher brain functions.

Researchers worked with 135 second-grade students at a school in Los Angeles after (24) _______ a pilot study with 102 students. Children that were given four months of piano training as well as time playing (25) _______ newly designed computer software scored 27 percent higher on math and fraction tests than other children.

Piano instruction is thought to enhance the brain’s “hard wiring” for spatial-temporal reasoning, or the ability to visualize and transform objects in space and time, says Professor Gordon Shaw, who led the study. At the same time, the computer game allows children to solve geometric and math puzzles that boost their ability to (26) _______ shapes in their mind.

The findings are significant (27) _______ a grasp of proportional math and fractions is a prerequisite to math at higher levels, and children who do not master these areas of math cannot understand move advanced math that is critical to high-tech fields.

(Adapted from “Eye on Editing 2” by Joyce S. Cain)

A. because.

B. unless.

C. before.

D. although.

Answer 1

Chọn đáp án A

The findings are significant because a grasp of proportional math and fractions is a prerequisite to math at higher levels, and children who do not master these areas of math cannot understand more advanced math that is critical to high-tech fields: Các phát hiện này rất quan trọng vì nắm được toán phân số và tỉ lệ là tiên quyết trong toán học ở các trình độ cao hơn, và những đưaá trẻ không nắm chắc các phần này không thể hiểu được toán nâng cao hơn, một phần quan trọng trong các lĩnh vực công nghệ cao.

Ta thấy sau vị trí trống là phần giải thích vì sao các phát hiện lại quan trọng, vậy nên liên từ “because” là phù hợp nhất. Vậy ta chọn đáp án đúng là A.
