Results of the norming study where each noun was presented together with a verb (e.g., traditsioon + jätkama, ‘tradition + continue’, otsing + jätkama, ‘search + continue’, investor + jätkama, ‘investor + continue’) and participants were asked to say whether all the nouns fit with the verb.

Two experiments were necessary because the first experiment did not deliver enough suitable items for the main experiment. (TEX)

鉴于首项实验未能提供足够适宜的样本以供主实验之需，因此有必要进行两项实验。
