… packages should always be handled with care

Analyze the question: The sentence needs an adjective that describes a type of package that must be handled carefully. We are looking for the word whose meaning explains why care is needed.

Explain the concept: This is a vocabulary-in-context question. Always test each option by putting it into the sentence and asking whether it makes logical and natural sense.

Solution: test each option

• A. Insecure packages: "Insecure" means not safe, not firmly fastened, or lacking confidence. It describes a poorly secured package, not one that needs gentle handling. It is not the natural choice.
• B. Fragile packages: "Fragile" means easily broken or damaged. Packages containing glass, ceramics, or electronics are labelled "FRAGILE - Handle with Care." This fits perfectly and is a standard collocation.
• C. Weak packages: "Weak" describes strength or power, such as a weak person or a weak argument. We do not normally describe packages this way.
• D. Boxed packages: "Boxed" only tells us how something is packed. It says nothing about why care is needed.

Answer: The correct option is B. Fragile.

"Fragile packages should always be handled with care" is logical, natural, and matches the labels you see on parcels at courier offices and in the post.

Exam tip: Look for collocations, words that naturally go together. "Handle with care" and "fragile" are almost always paired. When an English question seems tricky, read the sentence aloud with each option. The right answer usually sounds natural, and the wrong ones sound odd.
