choices.text: contact:communication:integration tiny:low:small quarrel:dispute:fight no cause:no reason:unreasonable
explanation: "conflict" may be caused by "contradiction", and "conflict" may lead to "war". "communication" may be facilitated by "contact", and "communication" may be promoted by "integration". "tiny" and "small" have similar meanings, and "low" does not lead to "small" "dispute" may be caused by "quarrel", and "quarrel" may lead to "fight", but the word order is inconsistent with the query. "no cause", "no reason" and "unreasonable" are similar in meaning, and "no cause" will not lead to "no reason"
