The two tasks were performed … and we were able to finish early.

Analyze the question

The sentence says: "The two tasks were performed __ and we were able to finish early." We need the adverb that explains why finishing early was possible.

Explain the concept

This tests vocabulary in context. Look at the clue after "and": we were able to finish early. That result suggests the tasks took less total time because they were done at the same time.

Meanings of the options:

• Alternatively: as another option or choice (not about timing of two tasks done together)
• Simultaneously: at the same time
• Consecutively: one after the other, in unbroken sequence
• Separately: apart from each other, individually

Step-by-step solution

1. Doing two tasks at the same time saves time, so finishing early makes sense.
2. Alternatively doesn't fit, because the tasks were both performed, not offered as choices.
3. Consecutively means one after another. That would take longer, so it doesn't logically lead to finishing early.
4. Separately only says the tasks were done apart, with no link to saving time.
5. Simultaneously fits best: the tasks were done together, so the work finished early.

Answer: B. simultaneously

Exam tip: Look for the cause-and-effect clue in the sentence. "Finish early" points to time-saving, so think "at the same time." Remember: SIMULtaneous = SIMILAR time, both words start with "sim".
