Read each hiding place off the picture and name the property:

(A) Ghulan — behind the brick wall → Opaque
(B) Sheeta — behind the tree trunk → Opaque
(C) Sara — behind the frosted glass door → Translucent
(D) Sheeta’s brother — at the glass window → Transparent

So the answer line reads: (A) Opaque (B) Opaque (C) Translucent (D) Transparent.

The three kinds of materials in Fig. 6.5: light from the lamp reaches the eye fully, partly, or not at all.

How to decide which is which: hold the material over a line of print in your book. If you can read the letters — transparent. If you can see that something is there but the letters are blurred — translucent. If you see nothing at all — opaque.
