Directions v The Caura River which is 449 miles long. __ into the Orinoco River. 17 A Mark for Review Which choice completes the text so that it conforms to the conventions of Standard English? A flow B have flowed C are flowing D flows

## Step 1<br />The sentence is discussing a general fact about the Caura River, which is that it flows into the Orinoco River. This is a general fact that does not change over time, so we need to use the simple present tense.<br />## Step 2<br />The verb "flow" in the simple present tense is "flows". Therefore, the correct choice is "D flows".<br />## Step 3<br />The other options "A flow", "B have flowed", and "C are flowing" are not appropriate in this context. "A flow" is not grammatically correct because the verb "flow" does not take an object. "B have flowed" is in the present perfect tense, which is used to describe an action that started in the past and continues in the present, which is not the case here. "C are flowing" is in the present continuous tense, which is used to describe an action that is happening at the moment of speaking, which is also not the case here.
