You will be given a definition of a task first, then some input of the task.
You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.

Paragraph- Sent 1: (CNN) -- Three human heads and three decapitated bodies with notes aimed at high government officials were found Thursday in different parts of Guatemala's capital, national police said.

Sent 3: One of the notes said the officials must impose order in the nation's prisons or these atrocities would continue, police said.
Sent 4: The other said that impunity against lawlessness must end, according to police.
Sent 5: The heads were inside plastic bags, one of them in front of the main doors to the national Congress in Guatemala City, police said.
Sent 6: "That's obviously a first for Guatemala," said Samuel Logan, an expert on Latin American gangs and founding editor of the Southern Pulse intelligence report.
Sent 7: "That's something we've seen the Zetas (drug cartel) do in Mexico."Sent 8: Donald Gonzalez, a spokesman for the national police, attributed the slayings to the Zetas or another narcotrafficking group, the Prensa Libre newspaper reported.

Sent 14: Logan said in an interview last year that there are two main criminal elements in Guatemala: drug cartels that deal in large-scale exportation and street gangs that sell drugs at the retail level and are involved in other crimes, such as robbery and extortion.
