1) Porch
○ "Attempt to porch lawmakers" → Incorrect (porch is a structure, not an action).
○ "Strive to porch public sentiment" → Incorrect (makes no sense).
2) Lobby
○ "Attempt to lobby lawmakers" → Correct (lobbying means influencing politicians).
○ "Strive to lobby public sentiment" → Incorrect (lobbying applies to officials, not public sentiment).
3) Sway
○ "Attempt to sway lawmakers" → Correct (sway means to influence).
○ "Strive to sway public sentiment" → Correct (swaying public opinion is a common phrase).
Thus, "Sway" is the only word that fits both blanks; "Lobby" fits only the first blank but not the second; "Porch" does not fit either blank.
Hence, the correct choice is (d) Only III.
