A.I. Explanation:

Question Focus: Detail question - asks what fish need in order to stay alive

Correct Answer: B

Passage Reference: In order to stay alive, animals need to have keen senses.

Why this is correct: The answer keen senses is correct because the speaker clearly explains what animals need to survive. You hear the speaker say that to stay alive, animals must have keen senses, and fish are included in this group.

Paraphrasing: Transcript: 'need to have keen senses' = Option: 'keen senses'

Tips: When you hear a clear definition sentence like 'In order to...', listen carefully because the answer often comes directly after it.

Why the other options are wrong:

• A: Students may choose nice colour because the speaker talks about fish colouring earlier. However, colouring is mentioned for hiding, not survival in general. This is a context shift trap.
• C: Students may think longer life sounds logical, but the speaker never says fish need a long life to survive. This idea is not mentioned at all. This is a Not Given style distractor.

Key Vocabulary:

• keen = sharp or strong
• senses = abilities to see, hear, feel

Question Focus: Detail question - asks what fish can do to survive

Correct Answer: C

Passage Reference: Fish and other sea animals can hear well and many of them can make different types of warning sounds.

Why this is correct: This is correct because the speaker explains another survival skill of fish. You hear that fish can make different types of warning sounds, which helps them survive danger.

Paraphrasing: Transcript: 'make different types of warning sounds' = Option: 'make various kind of warning sounds'

Tips: Listen for verbs after 'can'. What animals can do is often tested in detail questions.

Why the other options are wrong:

• A: Students may pick make a lot of water because water is discussed later in the lecture. However, that part is about humans, not fish. This is a context shift trap.
• B: Students might choose make many problems because it sounds active, but the speaker never says this. There is no mention of problems caused by fish. This is a Distractor trap.

Key Vocabulary:

• warning = signal of danger
• various = many different

Question Focus: Main idea question - asks the reason humans explore the sea

Correct Answer: C

Passage Reference: This is because the population of the earth is increasing so fast that very soon the land alone will not be able to provide enough food for everybody.

Why this is correct: The answer is correct because the speaker gives a clear reason. You hear that the population is increasing so fast that land alone will not be able to provide enough food, so humans turn to the sea.

Paraphrasing: Transcript: 'land alone will not be able to provide enough food' = Option: 'the land alone will not be able to provide enough food'

Tips: For 'why' questions, listen for signal phrases like 'This is because' or 'That is why'. The answer usually follows.

Why the other options are wrong:

• A: Students may choose people like seafood because it sounds logical in real life. However, the speaker never mentions preference or liking seafood. This is a Real-world knowledge trap.
• B: This option is tempting because the speaker does mention oil and minerals later. However, that is an extra detail, not the main reason humans explore the sea. This is a Partial truth trap.

Key Vocabulary:

• population = number of people
• provide = give or supply

General Tips:

• Questions follow the order of the recording, so use the previous answer to know when the next one is coming.
• Do not choose answers just because they sound logical in real life. Choose what the speaker actually says.
• Listen carefully after signpost phrases like 'This is because' or 'In order to'.
• The speaker may mention extra details that are true but not the main answer. Stay focused on the question.
• You hear the recording only once, so stay calm and keep listening even if you miss one word.
