Question

1. although the actor thought he did an excellent job __ his lines, he received several __ next day.

a. elucidating; lucid
b. improvising; providential
c. elucidating; translucent
d. improvising; invidious

1. even my modest, __ grandmother became as excited as a child when she saw the white __ with which we would make the dress.

a. photogenic; providential
b. lucid; phosphorescent
c. circumspect; translucent
d. invidious; phototropic

Explanation:

1. For question 4: "improvising" means creating or performing spontaneously, which makes sense for an actor's performance with lines. "invidious" means likely to arouse or incur envy. The other options' first - word "elucidating" (explaining clearly) is not as fitting for an actor's basic performance of lines, and the second - word choices in other options don't match the context as well.
2. For question 5: "circumspect" means wary and unwilling to take risks, which can describe a "modest" grandmother. "translucent" can describe the white material for the dress. The other word - combinations don't fit the context as well.

Answer:

1. D. improvising; invidious
2. C. circumspect; translucent
