1
The study is about the eating habits of children from 2 to 4 years old. It finds that not liking green vegetables is because of a child’s genes (基因).
2
The study finds that changes in two genes can make children dislike vegetables.
3
They become fussy (挑剔的) eaters. The study finds that the changes can affect (影响) how things taste (有……味道) to young children.
4
Children without these gene changes do not feel this way.
Natasha Cole, a researcher, says the study can help find new ways of helping children eat green vegetables.
5
A. We hope this study will work well.
B. A new study may give a reason for this.
C. Some children have the same genes as others.

解析：
我们可以根据上下文逻辑逐一匹配选项：
1. 空前描述了幼儿不爱吃青菜、家长很难让孩子健康饮食的现象，空后开始介绍相关研究，B选项“一项新的研究或许可以给出这个现象的原因”可以承上启下，符合语境。
2. 空前指出研究发现孩子不爱吃青菜是基因导致的，D选项“这意味着家长不必为此担忧”是该研究结论带来的合理推论，衔接自然。
3. 空前提到两种基因的变异会让孩子讨厌蔬菜，空后说明孩子会变成挑食的人，E选项“这些变异让孩子不愿意尝试新食物”解释了基因变异带来的行为变化，衔接前后内容。
4. 空前说明基因变异会影响孩子对味道的感知，空后说明没有这类基因变异的孩子不会有这种感受，F选项“这些孩子觉得很多绿色蔬菜尝起来非常苦”是味道感知受影响的具体表现，符合语境。
5. 空前提到这项研究可以帮助找到引导孩子吃青菜的新方法，A选项“我们希望这项研究能顺利起效”是对研究的后续展望，作为段落收尾合理。
多余选项C不符合任意空格的语境。
