   Not only does Polo threaten coastal areas, but it may bring heavy rain.

   Negative-fronted “not only” requires auxiliary inversion in the main clause.

3. Question 3 · Single choice

   2. If Nolo moved closer, flooding risks would still remained possible.

   4. If Nolo would move closer, flooding risks still remained possible.
   Check answers and explanations

   If Nolo had moved closer, flooding risks would still remain possible.

   The past condition contrasts with a present consequence using “would still remain.”

   4. Assessing the storms involves monitoring movement and to evaluate rainfall risks.

   The coordinated gerunds share the same grammatical form after “involves.”

6. Question 6 · Single choice

   Choose one answer.

   2. Officials recommend that residents remains alert to sudden flooding.
   3. Officials recommend residents remained alert to sudden flooding.
   4. Officials recommend that residents are remaining alert to sudden flooding.

   After “recommend,” formal American English permits the base verb “remain.”

   Moving away from Hawaii, Nolo may still produce intense rainfall.

   The participial clause logically refers to Nolo, the subject of the main clause.

What to review next

After checking an answer, explain the rule in your own words and write a new sentence using the same pattern. Revisit any rules you could not explain.
