\task A
\task B
\task C
\task D

output with pdflatex: enter image description here But I don't want the D choice goto the second line, I want them stay in one line, what should I do?

  • Welcome to TeX.SX! Please post a compilable MWE in your question, not just a code fragment. Adding your fragment to an MWE of my choise leads to a 4 column output. – alwaysask Oct 19 '16 at 11:10
  • @alwaysask Thanks for your advice. I still got two line with your code, what additional information should I attach? – Page David Oct 19 '16 at 11:48
  • Now your MWE needs an \end{document} at the end. Most likely your TeX installation needs an update. You can compile your code using online compilers to test the result against your installation -- for example on papeeria.com. – alwaysask Oct 19 '16 at 12:12
  • @alwaysask but I installed it with the latest ISO file yesterday... – Page David Oct 19 '16 at 12:26
  • Generally, ISO's don't get updated. Please point me to the link you downloaded the ISO and/or give details of your system (OS, TeX installation etc). – alwaysask Oct 19 '16 at 12:36
