Passage Reference: aemolyticus Origins Drinking water, shell

Common Mistake: Some students choose Salmonella because they think of food poisoning in general. This is a Context shift trap because Salmonella is linked to chickens and raw food, not seafood.

Paraphrasing: Passage: 'shellfish and fish' = Statement: 'seafood'

Tips: When you see a general word like seafood, scan for specific food examples like fish or shellfish.

Key Vocabulary:

• shellfish = seafood
• origins = where it comes from

Question Focus: Synonym match - 'dangerous for pregnant women' = 'may cause miscarriage and stillbirth'

Passage Reference: ys to 3 months Symptoms Flu-like symptoms: fever, headaches and pains. May cause miscarriage and stillbirth, meningitis and septicaemia F.

Why this is correct: The answer is Listeria monocytogenes. The passage says it may cause miscarriage and stillbirth, which clearly shows it is dangerous for pregnant women.

Common Mistake: Students sometimes choose Salmonella because it sounds serious. This is a Partial truth trap because Salmonella is serious, but pregnancy risk is not mentioned.

Paraphrasing: Passage: 'may cause miscarriage and stillbirth' = Statement: 'dangerous for pregnant women'

Tips: For pregnancy questions, scan quickly for words like miscarriage, stillbirth, or pregnant.

Key Vocabulary:

• miscarriage = losing a baby
• stillbirth = baby born dead

Question Focus: Number match - 'up to three weeks' = '3-21 days'

Passage Reference: s Symptoms Nausea, vomiting, stomach cramps, diarrhoea, fever and headache for 3-21 days B.

Why this is correct: The answer is Salmonella. The symptoms last 3-21 days, which is exactly up to three weeks.

Common Mistake: Some students choose Vibrio parahaemolyticus because it lasts several days. This is a Extreme language trap because several days is much shorter than three weeks.

Paraphrasing: Passage: '3-21 days' = Statement: 'up to three weeks'

Tips: Always convert days into weeks if the question uses weeks.

Key Vocabulary:

• symptoms = signs of illness
• up to = maximum

Question Focus: Specific detail match - pets mentioned directly

Passage Reference: . Campylobactor Origins Raw poultry, raw meats, untreated water, unpasteurised milk; puppies, kittens, wild

Why this is correct: The answer is Campylobactor. The origins include puppies and kittens, which are common household pets.

Common Mistake: Students sometimes choose Salmonella because animals are mentioned. This is a Context shift trap because it talks about animals as food sources, not pets.

Paraphrasing: Passage: 'puppies, kittens' = Statement: 'common household pets'

Tips: Words like puppies and kittens are strong clues. Do not ignore them.

Key Vocabulary:

• household pets = animals at home
• origins = source

Question Focus: Reverse meaning - humans only, not animals

Passage Reference: in) Origins Skin, nose, saliva, bowel of h

Why this is correct: The answer is Staphylococcus aureus. The origins list only humans and do not mention animals, so it is not usually found in animals.

Common Mistake: Students may choose Clostridium perfringens because soil is mentioned. This is a Reverse meaning trap because animals are clearly included there.

Paraphrasing: Passage: 'of humans' = Statement: 'not usually found in animals'

Tips: If animals are not mentioned at all, that often answers negative statements like this.

Key Vocabulary:

• usually = in most cases
• origins = where it lives

Question Focus: Two-part match - soil origin + fast onset

Passage Reference: ringens Origins Soil, bowel, intestine of humans and animals Onset 8-12 hours Symptoms Stomach pains, diarrhoea and sometimes nausea and vomiting. Lasts for about 24 hours D.

Why this is correct: The answer is Clostridium perfringens. It comes from soil, which links to gardens, and the onset is 8-12 hours, which means within a few hours.

Common Mistake: Some students choose Listeria monocytogenes because soil is mentioned. This is a Time/tense trap because Listeria can take up to 3 months to start.

Paraphrasing: Passage: 'Soil' and '8-12 hours' = Statement: 'garden' and 'within a few hours'

Tips: For two-clue questions, make sure both clues match the same option.

Key Vocabulary:

• soil = garden dirt
• onset = when it starts

General Tips:

• Matching Features can jump around the passage - do not assume the answers follow order.
• Scan for keywords like animals, soil, time numbers, or pregnancy risks.
• Convert time units carefully, such as days into weeks or hours into days.
• Options can be used more than once in matching features - do not cross them off automatically.
