Choose the most appropriate option to fill the blank in the given sentence. The tiny deer stood looking at them with ___ eyes.

Correct — A. The blank describes the deer's eyes, so it needs an adjective for how eyes look. Luminous means shining or glowing with light, a natural description of bright, glistening eyes.

'The tiny deer stood looking at them with luminous eyes' → option (a).

Why the others are wrong

• (b)
  Arid — Arid means very dry, used of land or climate with little rain, or figuratively of something dull ('an arid lecture'). Neither sense describes a deer's eyes.
• (c)
  Stationary — Stationary means not moving and is used of things like vehicles: 'a stationary car'. The deer already 'stood'; the blank asks how its eyes looked, and stationary says nothing about that.
• (d)
  Transparent — Transparent means see-through, like glass, or figuratively obvious ('a transparent excuse'). Neither sense describes how the deer's eyes looked.

A one-blank vocabulary item tests collocation: which adjective sits naturally with the noun. Eyes are described by how they look: bright, dull, sparkling, tearful, luminous.

The wrong options belong to other nouns: arid to land and climate, stationary to vehicles and objects, transparent to glass and water.

Luminous comes from Latin lumen, 'light'.

Key facts

• Luminous means full of or giving off light: bright or shining.
• Arid means very dry, having little or no rain.
• Stationary (not moving) is a different word from stationery (writing materials).
• Transparent means see-through, or figuratively obvious, as in 'a transparent excuse'.

Common traps

• Choosing stationary because the deer stood still — the blank describes the eyes, not the deer's position
• Choosing transparent to mean clear or bright — transparent means see-through
