Answer Key & Marking Scheme

Subject: Malay (Bahasa Melayu) Paper: Practice Paper — Comprehension & Language Use Total Marks: 50


Section A: Comprehension (20 marks)


Question 1 (1 mark)

Answer: Pemanasan global ialah fenomena peningkatan suhu purata permukaan bumi yang berpunca daripada pengumpulan gas rumah kaca seperti karbon dioksida (CO2CO_2) dan metana (CH4CH_4) di atmosfera.

Marking Notes:

  • Award 1 mark for a correct definition that includes the idea of "peningkatan suhu purata permukaan bumi" or equivalent.
  • Accept paraphrases that capture the core meaning.
  • Do not accept answers that only mention "suhu meningkat" without reference to the earth's surface or global context.

Question 2 (1 mark)

Answer: (i) Karbon dioksida / CO2CO_2 (ii) Metana / CH4CH_4

Marking Notes:

  • Award 1 mark for both correct answers.
  • Award 0 marks if only one gas is named or if both are incorrect.
  • Chemical symbols (CO2CO_2, CH4CH_4) are acceptable as answers.

Question 3 (2 marks)

Answer: Ekosistem marin terjejas kerana lautan menyerap lebih daripada 90 peratus haba berlebihan yang dihasilkan oleh aktiviti manusia, menyebabkan suhu laut meningkat secara berterusan.

Marking Notes:

  • Award 2 marks for a complete answer that explains both the absorption of excess heat AND the resulting increase in sea temperature.
  • Award 1 mark for mentioning only one aspect (e.g., only mentions heat absorption OR only mentions rising sea temperature).
  • The answer must be based on the passage — do not accept general knowledge answers not found in the text.

Question 4 (2 marks)

(a) Answer: Alga zooxanthellae menyediakan makanan kepada karang melalui proses fotosintesis dan memberikan warna yang indah kepada karang.

Marking Notes (a):

  • Award 1 mark for mentioning either "menyediakan makanan melalui fotosintesis" OR "memberikan warna kepada karang."
  • Both points together still earn 1 mark for part (a).

(b) Answer: Karang menjadi putih pucat kerana ia mengusir alga zooxanthellae apabila suhu laut meningkat melebihi julat toleransinya. Tanpa alga, karang kehilangan warna.

Marking Notes (b):

  • Award 1 mark for explaining that the algae are expelled/rejected due to high temperature, causing the coral to lose its colour.
  • Accept "mengusir alga" or "kehilangan alga" as the key idea.

Marking Notes:

  • Award 1 mark for mentioning the death of nearly half the coral at the Great Barrier Reef.
  • Accept "kematian hampir separuh karang" or equivalent phrasing.

Question 6 (2 marks)

Answer: Spesies marin berhijrah ke kawasan yang lebih sejuk (ke arah kutub atau ke laut yang lebih dalam). Perubahan ini mengganggu rantai makanan marin dan menjejaskan industri perikanan, menyebabkan penurunan tangkapan ikan yang memberi kesan kepada mata pencarian nelayan dan keselamatan makanan.

Marking Notes:

  • Award 1 mark for explaining the migration of marine species to cooler areas.
  • Award 1 mark for explaining the impact on humans (disruption to food chain / fishing industry / reduced fish catch).

  • Answers must be based on the passage.

Question 9 (2 marks)

Answer: Lautan menyerap kira-kira 30% CO2CO_2 yang dilepaskan ke atmosfera. Apabila CO2CO_2 larut dalam air laut, ia membentuk asid karbonik (H2CO3H_2CO_3), yang menurunkan nilai pH air laut. Proses ini dikenali sebagai pengasidaan laut.

Marking Notes:

  • Award 1 mark for providing two relevant supporting evidences from the passage.
  • Accept any two valid evidences from the passage that support the main message.
  • If the main message is not clearly stated but evidences are correct, award 1 mark only.

Section B: Summary Writing (10 marks)

Question 13 (10 marks)

Model Summary:

Pemanasan global yang disebabkan oleh gas rumah kaca meningkatkan suhu laut secara berterusan. Ini menyebabkan pemutihan karang apabila alga simbiotik diusir. Spesies marin berhijrah ke kawasan lebih sejuk, mengganggu rantai makanan dan mengurangkan tangkapan ikan. Pencairan ais kutub menaikkan aras laut, menyebabkan banjir dan hakiran pantai. Pengasidaan laut pula menghalang organisma membentuk cangkang. Langkah-langkah seperti Perjanjian Paris dan program penanaman bakau sedang dilaksanakan, tetapi tindakan besar-besaran diperlukkan untuk memulihkan ekosistem marin.

(Word count: approximately 80 words — accept summaries between 70–85 words)

Marking Scheme:

CriterionMarksDescription
Content6Award 1 mark for each valid content point included, up to 6 marks. Valid points include: (1) Gas rumah kaca meningkatkan suhu laut, (2) Pemutihan karang / pengusiran alga, (3) Spesies marin berhijrah / rantai makanan terganggu, (4) Penurunan tangkapan ikan, (5) Kenaikan aras laut / banjir / hakiran, (6) Pengasidaan laut / cangkang organisma terjejas, (7) Langkah pemulihan diambil (Perjanjian Paris / penanaman bakau), (8) Tindakan besar-besaran diperlukan
Language44 marks: Excellent use of own words, accurate grammar, fluent expression. 3 marks: Good use of own words with minor errors. 2 marks: Some lifting from passage, moderate language. 1 mark: Heavy lifting, frequent errors. 0 marks: Wholly lifted or incomprehensible.

Additional Notes:

  • The summary must not exceed 80 words. Deduct 1 mark from Language if the word count significantly exceeds 80.
  • Students should use their own words as far as possible. Direct lifting of phrases like "pemutihan karang" and "rantai makanan" is acceptable as these are technical terms, but extended verbatim copying should be penalised in the Language mark.
  • The summary should be coherent and not presented as bullet points.

Section C: Language Use & Grammar (20 marks)

Part 1: Vocabulary (5 marks)

Question 14 (1 mark)

Answer: C. berterusan

Explanation: "Berterusan" means continuously, which fits the context of sea temperature rising continuously beyond the coral's tolerance range. "Sengaja" (deliberately), "mendadak" (suddenly), and "perlahan-lahan" (slowly) do not accurately describe the process described in the passage.


Question 15 (1 mark)

Answer: A. aktif

Explanation: "Aktif" means actively, which matches the passage's statement that the mangrove planting program is being actively carried out. "Pasif" (passive), "perlahan" (slow), and "ragu-ragu" (hesitant) contradict the meaning.


Question 16 (1 mark)

Answer: A. dipulihkan

Explanation: "Dipulihkan" means restored/recovered. The sentence states that the loss of marine biodiversity will become irreversible ("tidak dapat dipulihkan") without immediate action. "Dihalang" (prevented), "dilindungi" (protected), and "dikawal" (controlled) do not fit the context.


Question 17 (1 mark)

Answer: B. menghalang

Explanation: "Menghalang" means to prevent/hinder. The passage states that ocean acidification prevents organisms from forming their shells. "Membantu" (help), "mempercepatkan" (accelerate), and "menggalakkan" (encourage) have opposite meanings.


Question 18 (1 mark)

Answer: B. menetapkan

Explanation: "Menetapkan" means to set/establish. The Paris Agreement 2015 set the target of keeping global temperature rise below 2°C. "Menghapuskan" (abolish), "mengurangkan" (reduce), and "melanggar" (violate) do not fit the context.


Part 2: Grammar — Sentence Transformation (5 marks)

Question 19 (2 marks)

Answer: Lebih daripada 90 peratus haba berlebihan yang dihasilkan oleh aktiviti manusia diserap oleh lautan.

Marking Notes:

  • Award 2 marks for a grammatically correct passive sentence that retains the original meaning.
  • Award 1 mark for attempting the passive transformation but with minor grammatical errors (e.g., incorrect word order or missing "oleh").
  • Award 0 marks for an incorrect transformation or for keeping the active voice.
  • Key elements: the object ("haba berlebihan") becomes the subject, "diserap" is used as the passive verb, and "oleh lautan" indicates the agent.

Question 20 (3 marks)

Answer: Pemutihan karang berlaku kerana suhu laut meningkat, menyebabkan alga zooxanthellae diusir daripada karang.

Alternative acceptable answer: Apabila suhu laut meningkat, pemutihan karang berlaku dan alga zooxanthellae diusir daripada karang.

Marking Notes:

  • Award 3 marks for a grammatically correct complex sentence that combines both ideas using an appropriate conjunction (e.g., "kerana," "menyebabkan," "apabila").
  • Award 2 marks for a sentence that combines both ideas but with minor grammatical errors or awkward phrasing.
  • Award 1 mark for attempting to combine the sentences but producing a run-on sentence or using an inappropriate conjunction.
  • Award 0 marks for not combining the sentences or for an entirely incorrect response.
  • Acceptable conjunctions: kerana, oleh sebab, menyebabkan, apabila, apabila...maka.

Part 3: Language in Context (10 marks)

Question 21 (3 marks)

(a) Answer: "Menekankan"

Marking Notes: Award 1 mark for identifying "menekankan" as the verb showing the importance of action.

(b) Answer: "Berskala besar" bermaksud dilakukan secara besar-besaran, meluas, dan melibatkan usaha yang menyeluruh pada peringkat yang besar.

Marking Notes: Award 1 mark for explaining that "berskala besar" means on a large scale / comprehensive / extensive.

(c) Answer: Acceptable synonyms: "menitikberatkan," "menyatakan dengan tegas," "menggariskan," "menegaskan."

Marking Notes: Award 1 mark for any appropriate synonym.


Question 22 (3 marks)

(a) Answer: simbiotik

Explanation: "Hubungan simbiotik" refers to the symbiotic relationship between coral and algae.

(b) Answer: toleransi

Explanation: "Julat toleransi" means the tolerance range — the temperature range that coral can withstand.

(c) Answer: drastik

Explanation: "Tindakan drastik" means drastic action — strong and far-reaching measures needed to address climate change.

Marking Notes: Award 1 mark for each correct answer. Total: 3 marks.


Question 23 (4 marks)

Model Answers:

(a) Pemuliharaan — Pemuliharaan hutan adalah penting untuk mengurangkan kesan pemanasan global.

(b) Antarabangsa — Kerjasama antarabangsa diperlukan untuk menangani isu perubahan iklim.

(c) Rangkaian makanan — Pengasidaan laut mengancam rangkaian makanan marin yang kompleks.

(d) Mata pencarian — Ramai nelayan kehilangan mata pencarian akibat penurunan tangkapan ikan.

Marking Notes:

  • Award 1 mark for each sentence (total: 4 marks).
  • Each sentence must: (i) use the given word correctly, (ii) be grammatically correct, (iii) have clear and logical meaning.
