5 soal pilihan ganda berikut diambil dari bank soal SekolahSMA, lengkap dengan pembahasan langkah demi langkah. Coba kerjakan dulu sebelum membaca pembahasannya.
SOAL 1
Read the following passage.
"Walking is one of the simplest forms of exercise, yet research consistently shows it brings substantial health benefits. A daily walk of 30 minutes can improve cardiovascular health, support healthy weight, and reduce the risk of several chronic conditions. Walking also requires no special equipment, no gym membership, and no expensive training. For these reasons, public health experts often recommend walking as the most accessible starting point for people who want to become more active."
What is the main idea of the passage?
A.Gym memberships are too expensive for most people to afford.
B.Walking requires expensive equipment to be effective.
C.Cardiovascular disease is the leading cause of death worldwide.
D.Public health experts disagree about the value of walking.
E.Walking is a simple and accessible exercise with substantial health benefits. ✓ Jawaban benar
Pembahasan
Every sentence supports one central claim: walking is simple, has health benefits, and is accessible. Option A captures all three pillars. B narrows to one detail (cost). C is unrelated. D contradicts the text. E contradicts "no special equipment".
SOAL 2
Read the following passage.
"School gardens have been introduced in many cities to support both nutrition education and ecological awareness among students. Children who participate in maintaining a garden often try a wider variety of vegetables, including ones they previously refused at home. Teachers also report stronger collaboration among students who share garden tasks. In some schools, the harvest is used directly in the cafeteria, closing the loop between growing and eating."
Which sentence best states the main idea?
A.Gardens are difficult to maintain in school environments.
B.Cafeteria food is generally low in quality everywhere.
C.School gardens aid nutrition, ecology, and student collaboration. ✓ Jawaban benar
D.Most students refuse to eat vegetables at home.
E.Teachers do not benefit from school garden programs.
Pembahasan
The opening sentence states "support both nutrition education and ecological awareness", and supporting sentences add the collaboration and farm-to-cafeteria angles. Option A captures all three benefits the passage credits to school gardens. B, C, D, E are details misread or fabricated.
Rincian jawaban C: School gardens support nutrition education, ecological awareness, and student collaboration.
SOAL 3
Read the following passage.
"Many small bookshops have responded to online competition by changing what they offer. Some host weekly author events, others organize book clubs that meet in their stores, and a few rent out part of their space for community classes and creative workshops. These shops are no longer purely places to buy books; they have become small cultural hubs. The shift has helped a number of independent stores survive even as overall book sales remain dominated by online platforms."
What is the best title for this passage?
A.A History of the Largest Online Book Retailers
B.How Small Bookshops Reinvented Themselves as Cultural Hubs ✓ Jawaban benar
C.Why All Independent Bookshops Have Already Closed
D.How to Open a Profitable Online Bookstore
E.The Decline of Reading in the Digital Age
Pembahasan
The passage describes specific shifts (events, book clubs, workshops) that turned bookshops into cultural hubs and helped them survive. Option A captures both the change and its outcome. B is unrelated. C is the wrong subject. D contradicts the survival mention. E is irrelevant content.
SOAL 4
Read the following passage.
"Sleep researchers have begun paying attention to a less obvious factor in adolescent sleep deprivation: school start times. Many secondary schools begin classes before 7:30 a.m., yet adolescent biological clocks shift later during puberty, making it physiologically difficult for them to fall asleep early enough to feel rested. When some districts moved start times to after 8:30 a.m., student attendance improved and academic performance edged upward, suggesting that the timing change addressed a real biological mismatch."
What is the main idea of the passage?
A.Academic performance is purely determined by individual student effort.
B.Sleep researchers should focus on adult sleep patterns instead.
C.Schools should start as early as 6:00 a.m. to maximize learning.
D.Early starts clash with teen biology; later starts improve outcomes. ✓ Jawaban benar
E.Adolescents do not need much sleep compared to younger children.
Pembahasan
The passage builds a clear argument: biological clocks shift later -> early starts mismatch -> later starts improved attendance and performance. Option A captures both the mismatch and the outcome. B contradicts the biology mention. C ignores the structural finding. D and E run opposite to the passage.
Rincian jawaban D: Early school start times conflict with adolescent biology, and later starts improve student outcomes.
SOAL 5
Read the following passage.
"Public libraries today are far more than book repositories. Modern libraries offer free internet access, computer training for older adults, language exchange meetups, free children's story hours, and quiet spaces for remote workers and students who lack stable home environments. In many neighborhoods, the library functions as one of the few remaining indoor public spaces that does not require any spending to enter."
What is the main idea of the passage?
A.Libraries are multi-purpose community spaces, not just book rooms. ✓ Jawaban benar
B.Libraries should charge entry fees to fund modern services.
C.Older adults rarely visit public libraries today.
D.Reading books is the only activity that should be allowed in libraries.
E.Public libraries are quietly being shut down across most countries.
Pembahasan
The passage opens with the main claim ("more than book repositories") and lists supporting examples (internet, computer training, language exchange, story hours, quiet spaces). Option A captures the multi-purpose framing precisely. B is unsupported, C contradicts the multi-service framing, D contradicts the computer-training mention, E contradicts the "no spending to enter" line.
Rincian jawaban A: Public libraries serve as multi-purpose community spaces, offering far more than just books.
