Question

Fill in the blank with the correct modal that expresses a strong desire:
I remember my promise. I _____ help you in the hour of need.
a) can
b) may
c) will
d) might

Answer 1

Hint: Look for pointers suggesting which modal auxiliary to use. The action has not occurred in the given sentence, i.e. it occurs in the future. These pointers are indicators of certain situations.

Complete answer:
 A modal verb is a type of verb that is used to indicate modality – that is: likelihood, ability, permission, request, capacity, suggestions, order, obligation, or advice. We need to find the verb from the options that indicate suggestions.
We can discern whether the actions are happening right now by certain pointers that are given in the sentence in the question. So, let us deconstruct the given sentence.
In the first part, the sentence is telling us that the person remembers their promise. They plan to help the other person in their hour of need. This expresses a strong desire, as mentioned in the question. So, we need to look for a modal verb expressing that meaning. It also tells us that the action will likely happen in the future.

Now, we know what we are looking for. Let’s look at the given options-
a) can - This modal auxiliary is most often used to express a person or thing's ability to do something. This does not fit into the context of the given sentence as it does not indicate a strong desire. This is not the required answer. So, this is an incorrect option.
b) may - This modal auxiliary is most often used to express a possibility. This does not fit into the context of the given sentence as it does not indicate a strong desire. This is not the required answer. So, this is an incorrect option.
c) will - This modal auxiliary is most often used to express a strong desire. This fits into the context of the given sentence as it does indicate a strong desire. This is the required answer. So, this is the correct option.
d) might - This modal auxiliary is often used to express a possibility. This does not fit into the context of the given sentence as it does not indicate a strong desire. This is not the required answer. So, this is an incorrect option.

Note:
 Choose the most appropriate option given the context of the sentence. Make sure all the forms of the verb are aligning with each other and work with each other perfectly.
