Final answer:
Jose should use DNA testing to identify Romulus from Remus.
Step-by-step explanation:
In this case, Jose should use a method of identification called DNA testing to tell Romulus from Remus. DNA testing is a highly accurate and reliable method of identification that compares the DNA profiles of two individuals to determine if they are identical or fraternal twins. Since Romulus and Remus are identical twins, their DNA profiles would be nearly identical. By comparing the DNA of the surviving twin with the DNA of the deceased twin, Jose can determine which twin is which.
