Teacher:Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Teacher: Now, understand the problem? Solve this instance: Abstract: Random-dot stereograms were found to be capable of producing fusional vergence amplitudes in the absence of monocular contours. These vergence amplitudes are not an artefact of monocular contours provided by the target borders or test instrument and are comparable in range to vergence amplitudes measured clinically with second degree fusion targets in an amblyoscope. We conclude that diplopia of monocularly recognisable contours is not necessary for producing fusional vergence amplitudes.
Which is the apt title for the abstract? option1: Vergence amplitudes with random-dot stereograms. option2: Coronary vasodilation by nitrates is not mediated by the prostaglandin system: a quantitative cineangiographic study.
Student:
Vergence amplitudes with random-dot stereograms.
