Hi,
Would you say that the underlined modal "could" denotes possibility, something like "could happen" in this sentence? And the modal "can" sort of denotes ability?
Can you think of anything more wonderful that could happen to you than receiving Christ?
Would you say that the use of "would be able to" and "could" in sentences is almost identical and a person should not be reticent to use them interchangeable in most sentential situations people normally encounter?
Would you be able to come to the meeting? -- Same?? as "Could you come to the meeting?"
Will you be able to come to the meeting -- More certain in implications than "would you be able to" or "could"?
