Explanation:

Analyze the first question on sanitation

The first visible question (partially cut off at the top) lists options related to environmental health and sanitation:

• A. good sanitary conditions.
• B. free drainage system.
• C. improper drainage system.
• D. irregular refuse disposal.

Based on standard home economics and environmental health curricula, issues like disease outbreaks or pest infestations are typically caused by "improper drainage system" or "irregular refuse disposal", while healthy living is promoted by "good sanitary conditions" and a "free drainage system". Since the question stem is cut off, we look at the most direct associations. However, we can fully solve the two complete numbered questions below.

Analyze Question 22

The question asks: "Cleaning substances are generally called"

• A. detergents.
• B. soap.
• C. softeners.
• D. starch.

In home economics and laundry care, "detergents" is the general term used for chemical substances or mixtures used for cleaning, which includes both soaps and synthetic detergents. Therefore, option A is the most appropriate general classification.

Analyze Question 23

The question asks: "The laundry agent that should only be used on natural white fabric is"

• A. bleach.
• B. detergent.
• C. dye.
• D. stiffeners.

Chemical bleaches (especially chlorine bleach) are strong oxidizing agents used to whiten fabrics. They can easily strip color from dyed fabrics and damage certain synthetic fibers, meaning they should generally only be used on natural white fabrics (like cotton or linen) to restore brightness and remove stains safely. Thus, option A is the correct answer.
