d. Because we forgot our gloves, we couldn't build the snow fort outside.

To determine which sentences have correctly placed commas, we need to review the rules for comma usage and apply them to each sentence. Here are the sentences provided, along with an explanation of the correct comma placement:

a. "During the dig, the construction workers made sure to wear their safety gear."
- Correct comma placement: The comma is placed after the phrase "the dig" to separate it from the main clause.

b. "After the lights were turned down, the movie began."
- Correct comma placement: The comma is placed after the phrase "the lights were turned down" to separate it from the main clause.

c. "I chose to adopt a Labrador puppy, my favorite type, from the shelter."
- Incorrect comma placement: The comma after "adopt a Labrador puppy" is unnecessary and creates a separation in the main clause that disrupts the sentence flow.

d. "Because we forgot our gloves, we couldn't build the snow fort outside."
- Correct comma placement: The comma is placed after the dependent clause "Because we forgot our gloves" to separate it from the main clause.

e. "My sister trained a bus driver volunteered to drive us to the store."
- Incorrect comma placement: There is no comma needed in this sentence. It seems to be missing a conjunction or proper punctuation to separate the clauses.

Based on the explanations above, the two sentences with correctly placed commas are:
a. During the dig, the construction workers made sure to wear their safety gear.
d. Because we forgot our gloves, we couldn't build the snow fort outside.
