Understanding the Butterfly Passage and Blank 4

The question asks us to complete a passage about butterflies by filling in five blanks with the most appropriate words. We are specifically focused on filling blank number 4.

Let's look at the sentence containing blank 4:

"The colours and patterns (2) ______ a butterfly’s wings (3) ______ them to blend (4) ______ its surrounding and protects it from its predators."

This sentence discusses how the colours and patterns on a butterfly's wings help it survive. The key verb here is "blend". When something blends, it becomes difficult to distinguish from its environment.

The phrase "blend (4) ______ its surrounding" describes how the butterfly uses its colours and patterns for camouflage, making it hard for predators to spot it within its habitat.

Analyzing Options for Blank 4: Blend and Prepositions

We need to choose the preposition that correctly completes the phrase "blend ______ its surrounding". Let's examine the options provided:

1. in
2. at with
3. with
4. in with

• Option 1: in - If we use "in", the phrase becomes "blend in its surrounding". While "blend in" is a common phrase meaning to appear similar to surroundings, it is usually followed by "with" or "to". For example, "blend in with the crowd" or "blend into the background". "Blend in its surrounding" is grammatically awkward.
• Option 2: at with - Using "at with" results in "blend at with its surrounding". This combination of prepositions makes no grammatical sense in this context.
• Option 3: with - Using "with" results in "blend with its surrounding". This is grammatically possible. "Blend with" can mean to mix or merge, which fits the idea of camouflage where colours blend with the environment. However, "blend in with" or "blend into" are often more specifically used for camouflage where something becomes indistinguishable from its surroundings.
• Option 4: in with - Using "in with" results in "blend in with its surrounding". The phrase "blend in with" is a very common and appropriate idiom used to describe camouflage or making something indistinguishable from its background. It perfectly fits the context of the butterfly's colours helping it hide from predators within its environment.

Selecting the Most Appropriate Option for Blank 4

Comparing the options, "blend in with" is the most natural and grammatically correct phrase to describe a butterfly using its colours and patterns for camouflage within its surrounding environment. It clearly conveys the idea of becoming hard to see against the background.

Therefore, the most appropriate option to fill blank number 4 is "in with".

Additional Information: Butterfly Camouflage and Predation

Butterflies use various strategies to avoid being eaten by predators like birds, lizards, and insects. Camouflage is one of the most important methods. The patterns and colours on their wings can look like leaves, bark, or other parts of their habitat, allowing them to "blend in with" their surroundings.

Some butterflies also use mimicry, looking like other species that are poisonous or taste bad to predators. Others have bright, warning colours if they are indeed toxic. The passage highlights the role of colours and patterns in helping the butterfly "blend in with" its environment for protection.

Understanding how prepositions work with verbs like "blend" is important for English grammar and reading comprehension.
