Answer:
She saw the people of the reserve with disgust and is uncomfortable and disgusted by everything she is seeing, mainly because of the amount of garbage and flies. From inside the reserve she can see the buildings in Malpais and condemns them as "queer", since they seem totally out of place from where she is.
Step-by-step explanation:
This question is about "Brave New World" a novel about a futuristic society completely modified and that presents the equality between all classes through a constant process of manipulation and limitation. In this book, we meet the character Lenina, who is a member of this futuristic society and who is very well established in the way of life that society establishes. One day Lenina is taken to Malpais, a reserve of people who live completely contrary to the rules of the society to which Lenina is a member. In Malpais people live without any control and behave in a primitive and wild way.
Lenina thinks Malpais is strange, filthy and disgusting. She sees the buildings as "queer" without technology, stinky and unpleasant. This is also her thinking about people and the bucolic environment. She holds this view for a long time, because she was taught and conditioned to believe that only the way she lived was the right one.
