Question

complete the sentence to maintain parallel structure. when malik and joseph went on a birdwatching expedition last weekend, they spent their days creating an inventory of endangered species, conservation efforts, and to ecological databases.

Explanation:

To solve this, we need to maintain parallel structure, which means the verb forms should be consistent. The first action is "creating" (a gerund, -ing form). So we need to use gerunds for the other blanks.

Step 1: Analyze the first blank

The first blank is after "creating an inventory of endangered species," and before "conservation efforts." The structure should be a gerund (verb + -ing) to match "creating". So a suitable verb could be "monitoring" (as in monitoring conservation efforts).

Step 2: Analyze the second blank

The second blank is after "and" and before "to ecological databases." The structure should also be a gerund. A suitable verb here could be "contributing" (as in contributing to ecological databases, since "contribute to" is a common phrase, and using the gerund "contributing" maintains parallelism with "creating" and "monitoring").

So the completed sentence would be: When Malik and Joseph went on a birdwatching expedition last weekend, they spent their days creating an inventory of endangered species, \boldsymbol{monitoring} conservation efforts, and \boldsymbol{contributing} to ecological databases.
