Step-by-step explanation:
Based on the provided information, it is unclear whether he donated a tract of land for the Cavite State University. The information provided does not directly mention whether he donated land for that specific university. However, it does mention that the federal government used land grants to support various projects, including universities and colleges. Some institutions, like Oklahoma State University, are land-grant institutions because their campuses were built on land donated by the federal government. Therefore, it is possible that land grants were used to support the establishment of Cavite State University, but further research would be needed to confirm this.
