Difficulty: Easy
Correct Answer: At the outer corner of the eye behind the upper eyelid
Explanation:
Introduction / Context:The passage explains how blinking and tear production help keep the eye clean and moist. It mentions the lachrymal or tear glands, describes their size and shape, and then states their position relative to the eyelid and eye. The question asks for the precise location of these glands based on the passage.
Given Data / Assumptions:
Concept / Approach:This is a location based comprehension question. The candidate must accurately recall the description of the position of the tear glands. It is important not to confuse the outer corner, where the glands are located, with the inner corner, where the tear duct drains the liquid into the nose. The best approach is to visualise the eye and then match this visual to the textual description.
Step-by-Step Solution:
Step 1: Revisit the sentence that begins “Each tear gland is about the size and shape of an almond.” Step 2: Read the very next line, which states that these glands are situated behind the upper eyelid at the outer corner of the eye. Step 3: Note that “behind the upper eyelid” and “outer corner of the eye” are both essential parts of the description. Step 4: Compare this wording with the options offered. Step 5: Choose option c, which accurately mentions “at the outer corner of the eye behind the upper eyelid.”Verification / Alternative check:We can further verify by comparing this information with the later sentence about drainage of tears. The passage explains that after washing the eye, the liquid is drained into the nose through the tear duct at the inner corner of the eye. So the glands and the draining duct are deliberately placed at opposite corners. This contrast helps confirm that the glands are at the outer corner, not the inner corner, and certainly not inside the eyeball itself.
Why Other Options Are Wrong:
Common Pitfalls:Students often confuse the role of the tear duct with the position of the tear glands. Because the duct is at the inner corner, some candidates mistakenly put the glands there as well. Another pitfall is to ignore the phrase “behind the upper eyelid,” which gives depth information. Paying close attention to each phrase in description based questions is essential.
Final Answer:At the outer corner of the eye behind the upper eyelid is the correct answer, because this is exactly how the passage describes the position of the lachrymal glands.
