    "do" or "have done"; "be" or "have been"?

    I get four sentences listed below which are related to NONFINITE VERB:
    Group A

    1. Charles Babbage is generally considered to invent the first computer.
    2. Charles Babbage is generally considered to have invented the first computer.
    Group B
    3. Peter is considered to be the first employee to arrive at the company.
    4. Peter is considered to have been the first employee to arrive at the company.
    Group C
    5. Mary Goddard is considered to hold a federal position when she lived in Baltimore.
    6. Mary Goddard is considered to have held a federal position when she lived in Baltimore.
    First, I would like to know which is the correct answer of each group.
    Second, I really really appreciate that if anyone cane help me figure out where "do" and "be" work better and where "have done" and "have been" are better when they function as NONFINITE VERBs?
    Deep thanks for any answer.

    When standing alone, do and be are present tense verbs. Combined with other verbs, they might be present, past, or future tenses. Have done and have been are never present tense.

    In American English, your use of considered is good but not quite as natural as other verb choices. I don't know how the British use it.

    Anyhow, I've showed you a few other verb choices you might like to use sometimes.

    I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.

    The second answer is right in every case.
