Answer 3

Concept:
• This is a factual reading comprehension question based on Paragraphs 2 and 3.
• The question requires identifying two pieces of evidence showing how the researchers conducted the study across different age groups.
• The answer should be based on the methodology and survey examination described in the passage.
• Since the question asks for two points, both should be mentioned clearly.

Step 1: Read Paragraphs 2 and 3 carefully.
Paragraph 2 explains the methodology adopted by the researchers. It describes where the study was conducted and how the information was collected. Paragraph 3 explains how the participants were divided and what nutritional aspects were examined.

Step 2: Identify the first supporting point.
The researchers selected participants from a wide range of institutions, including:
• five schools,
• two universities,
• three workplaces, and
• two retirement communities. This ensured that people belonging to different stages of life were included in the study.

Step 3: Identify the second supporting point.
The participants were further classified into four different age categories:
• Children (6--12 years),
• Adolescents (13--19 years),
• Adults (20--59 years), and
• Elderly (60+ years). The researchers then assessed their intake of macronutrients, micronutrients, hydration habits, and meal frequency. This helped compare the nutritional requirements of each age group.

Step 4: Write the final answer.
Answer: The case study explored various age groups by:
• conducting the study across schools, universities, workplaces, and retirement communities, and
• dividing participants into children, adolescents, adults, and the elderly while analysing their nutritional intake, hydration habits, and meal frequency.

Answer 4

Concept:
• This question tests the understanding of contextual vocabulary.
• The reader must classify the given sentences according to the ideas of development and prevention.
• Development refers to promoting growth or improvement.
• Prevention refers to avoiding a problem or protecting against a harmful condition.

Step 1: Read Sentence A carefully.
Sentence A: “Children had higher energy and protein needs per kilogram of body weight, essential for growth.” The emphasis is on providing nutrients that support physical growth and healthy body development. Therefore, this sentence represents the idea of development.

Step 2: Read Sentence B carefully.
Sentence B: “Adolescents need increased calcium so that their bone growth is not impacted.” The sentence focuses on ensuring that bone growth is protected from being affected negatively. Thus, it highlights the idea of preventing a health problem. Hence, it represents prevention.

Step 3: Classify both statements.
The first statement promotes healthy growth. The second statement focuses on avoiding harm to bone development. Hence, they belong to different categories.

Step 4: Write the final answer.
Answer:
• Sentence A -- Development
• Sentence B -- Prevent

Answer 5

Concept:
• This is a direct reading comprehension question based on Paragraph 4.
• The answer should be taken directly from the information provided in the passage.
• Fibre is an important nutrient that supports proper digestive functioning.
• Elderly people require additional fibre because their digestive system becomes less efficient with age.

Step 1: Locate the relevant information in Paragraph 4.
Paragraph 4 explains the nutritional requirements of different age groups. Regarding elderly people, the passage states that they require more fibre, calcium and Vitamin D.

Step 2: Identify the reason given by the author.
The author specifically mentions that additional fibre is required to support healthy digestion. As people grow older, digestion generally slows down, making fibre-rich foods more important.

Step 3: Form the complete answer.
The answer should clearly mention the reason stated in the passage without adding unnecessary details.

Step 4: Write the final answer.
Answer: Although all age groups require a balanced diet, the elderly need more fibre because it helps support healthy digestion and maintains proper digestive function.

Answer 6

Concept:
• This is a Multiple Choice Question based on Paragraph 5.
• The answer depends upon understanding the purpose of hydration reminders.
• Hydration reminders are designed to encourage regular water intake and prevent dehydration.
• The correct option should match the author's intended purpose.

Step 1: Read the relevant statement carefully.
Paragraph 5 states: “Across all groups, hydration reminders were implemented using digital tools and scheduled water breaks.”

Step 2: Understand the purpose of hydration reminders.
Hydration reminders encourage people to drink water at regular intervals. Their objective is to maintain proper hydration and prevent dehydration.

Step 3: Evaluate each option.
Option (A): Hydration reminders help ensure that people drink enough water and do not become dehydrated. This exactly matches the purpose mentioned in the passage. Hence, this is the correct answer. Option (B): Hydration has no direct connection with preventing starvation. Therefore, this option is incorrect. Option (C): The passage never mentions weight loss as the purpose of hydration reminders. Hence, this option is incorrect. Option (D): Hydration reminders are unrelated to balancing processed food consumption. Therefore, this option is also incorrect.

Step 4: Select the correct option.
Since hydration reminders are intended to encourage regular water intake and prevent dehydration, the correct answer is \[ \boxed{(A) ensure people did not get dehydrated \]

Answer 7

Concept:
• This is an evidence-based comprehension question.
• The answer requires both an explanation and supporting textual evidence.
• The explanation should state why age-specific nutrition is necessary.
• The textual evidence should be taken directly from the passage.

Step 1: Identify the main idea.
The passage explains that nutritional needs are not the same for everyone. They vary according to age because each stage of life has different physical, cognitive, and lifestyle requirements.

Step 2: Locate the supporting evidence.
The concluding paragraph clearly states: “Nutritional needs vary significantly with age, influenced by physical, cognitive, and lifestyle factors. Regular assessments and tailored interventions are essential for promoting long-term health across populations.” This statement directly supports the importance of age-specific nutrition.

Step 3: Combine explanation and evidence.
Different age groups require different nutrients for growth, maintenance, disease prevention, and healthy ageing. Therefore, diets should be planned according to age.

Step 4: Write the final answer.
Answer: Age-specific nutrition is important because nutritional requirements change with different stages of life and help support healthy growth, development, and overall well-being. Textual Evidence: “Nutritional needs vary significantly with age, influenced by physical, cognitive, and lifestyle factors. Regular assessments and tailored interventions are essential for promoting long-term health across populations.”
