It should be truthful. Winning an argument or answering a question through deceit has little merit. It certainly doesn't win God's favour nor does it do the hearer much good. They sooner or later sees through it. Every answer must take into consideration the person it is directed to.
Human interchange requires more than a string of unfeeling, cold, hard facts.
We live in the era of fast answers. The simple, quick answer is fine if we can elaborate when called on to do so. Thus we must continually advance our knowledge in our faith, otherwise our answers will be superficial and obviously so. Many times there is something more to a question or statement than meets the eye. It should be gospel orientated.
