Expect dynamic input from bash

Question

Assume the following bash script, questions.sh:

#!/bin/bash
echo "Hello, who are you?"
read REPLY

and the following expect script:

#!/usr/bin/expect -f
spawn ./questions.sh # start our script using spawn command
expect "Hello, who are you?\r"
send -- "Im Adam\r"

The expect script acts as an answering robot to the shell script. Now assume that that I need to generate some answers dynamically. For instance, let's say that I want to feed the output of another shell script (answers.sh) as an answer. How would I have to modify the expect script? I tried the following but does not seem to work:

#!/usr/bin/expect -f
spawn ./questions.sh # start our script using spawn command
expect "Hello, who are you?\r"
send ./answers.sh

Answer 1

I figured it out:

#!/usr/bin/expect -f
spawn ./questions.sh # start our script using spawn command
expect "Hello, who are you?\r"
set answer [exec ./answer.sh]
send $answer
