    semantic concerns

    ---- when we interfere with planetary processes on a large scale.

    A) Climate change would almost certainly be accelerated
    B) We were extremely lucky that industrialists chose to use chlorine compounds not bromine
    C) The polar regions were adversely affected too
    D) We know surprisingly little about the risks we are running
    E) Aerosol emissions stay in the atmosphere for only a few days


    D seems to be correct. Do you think there would be any semantic oddness if D was inserted in the sentence? and what does the sentence mean?

    Re: semantic concerns

    D is correct. There wouldn't be any odd meaning that comes from combining the two parts.

    The sentence basically means that we do not know exactly what could happen if we were to change the world in a significant way. For example, burning the rainforests would be significant, and although we have an idea of what would happen, we don't know precisely.

    Re: semantic concerns

    Additionally, here are the reasons (why) choices A), B), C), and E) do not work in that context.

    ____________ when we interfere with planetary processes on a large scale.

    A) Climate change would almost certainly be accelerated
    => OK with "if we interfered with . . . "

    B) We were extremely lucky that industrialists chose to use chlorine compounds not bromine
    => OK with "were" (past) + "when we interfered" (past)

    C) The polar regions were adversely affected too
    => OK with "were" (past) + "when we interfered" (past)

    E) Aerosol emissions stay in the atmosphere for only a few days
    => Only "a few days"? Gee, phrase it that way and Aerosol emissions don't seem all that harmful to planetary processes.
