A question about True/False choice test

[Hyeonah]

Hi Grace,
Thanks for your advice!
Here's what I did in the trial.

"comp_2": {
"type": "basic",
"stimuli": [
{"which":["comp2-T"],"location":[2]}
],
"responses": ["T"],
"auto_advance": false
},

But the text ("comp2-T") doesn't move up but just appears in the middle.
Could you let me know how I should fix the code?
