In the following question, select the synonym (word most similar in meaning) of "streak".

Introduction / Context:
This vocabulary question asks for a synonym of the word "streak". The word can have several meanings depending on context, but the options given here point mainly toward its meaning as a mark or line. You must select the option that best matches this sense.

Given Data / Assumptions:

• Target word: "streak".
• Options: "freak", "bright", "immaculate", "smear", "blemish".
• We assume the physical sense of "streak" as in a long line or mark of a substance.
• The correct synonym should match this common meaning.

Concept / Approach:
The noun "streak" can mean a long, thin mark, smear, or line of colour or dirt. For example, "streaks of mud" or "a streak of blood". In this sense, "smear" is very close in meaning—a dirty mark or spot made by smearing a substance. The other options do not convey the idea of a long thin mark; "freak" relates to unusual behaviour or person, "bright" relates to light or intelligence, "immaculate" means extremely clean, and "blemish" is a general imperfection, not specifically a streak.

Step-by-Step Solution:
Step 1: Identify the likely meaning tested here: "streak" as a visible line or mark of something.Step 2: Compare each option: "freak" (odd person), "bright" (shining), "immaculate" (spotless), "smear" (dirty mark), "blemish" (flaw).Step 3: Notice that "smear" refers specifically to a marking caused by spreading a substance, similar to a streak of dirt or paint.Step 4: Recognise that "blemish" is more general and does not specifically indicate a linear mark.Step 5: Therefore, choose "smear" as the closest synonym of "streak" in the context of marks.

Verification / Alternative check:
Use sample sentences: "There were streaks of mud on the wall" is quite similar in meaning to "There were smears of mud on the wall." Both sentences describe lines or patches of mud. However, "blemishes of mud" would sound odd, and "freak", "bright", or "immaculate" simply do not fit in such a context. This confirms that "smear" is the nearest synonym from the given options.

Why Other Options Are Wrong:

• freak: Refers to an unusual event or a strange person; it has nothing to do with marks or lines.
• bright: Describes light, colour, or intelligence, not a physical mark.
• immaculate: Means perfectly clean, without any dirt or marks; it is more like the opposite of "streaky".
• blemish: A defect or imperfection on a surface, often used for skin or reputation; it is more general and not specifically a long thin mark.

Common Pitfalls:
Some students may pick "blemish" because they associate both words with imperfections. However, exam questions often focus on the more specific sense. "Streak" evokes a line like mark, which is much better captured by "smear" when we think of real life examples such as streaks of paint or dirt on a surface.

Final Answer:
The synonym of "streak" in this context is smear.
