Final answer:
The passenger manifest is unable to answer certain questions raised in the texts due to its limited scope and inability to provide insights into experiences, perceptions, and emotions.
Step-by-step explanation:
The question is asking about the reliability and helpfulness of the passenger manifest in relation to answering certain questions in the texts "On Seeing England for the First Time" and "Midsummer". The passenger manifest is unable to answer some of the questions raised in these texts because it only provides information about the passengers on a ship or plane and their basic details. It does not provide insights into their experiences, perceptions, or emotions which are important for understanding the themes and perspectives expressed in the texts.
