How does a later clue define the missing word?
Researchers have struggled to pinpoint specific causes for hiccups, which happen when a person’s diaphragm contracts . However, neuroscientist Kimberley Whitehead has found that these uncontrollable contractions may play an important role in helping infants regulate their breathing.
Which choice completes the text with the most logical and precise word or phrase?
- involuntarily
- beneficially
- strenuously
- smoothly
Answer: A. involuntarily
- Find the phrase "uncontrollable contractions" in the second sentence. It describes the same diaphragm contractions as the first sentence, so predict "without conscious control" before checking the choices.
- Choose A, "involuntarily." It expresses lack of voluntary control. Read the sentence again with that word: the later description confirms the meaning.
Common trap
Do not choose "beneficially" merely because the passage later mentions a possible benefit for infants. The blank describes how the contractions occur. "Strenuously" describes effort and "smoothly" describes evenness; neither is supported by the clue "uncontrollable."
