Much vs Many: Choose by Amount or Separate Items
Many goes with plural countable nouns. Much goes with singular uncountable nouns. Check how English treats the noun in this sentence before you choose.

The practical decision is not to translate the whole sentence first. Look at the noun connected to the blank: is it a plural countable noun, or an uncountable noun?
The core choice
Many = countable items
Use many with plural nouns for people or things that English treats as separate countable items: many employees, many reports, many questions, many changes.
Much = uncountable amount
Use much with singular uncountable nouns: much time, much information, much money, much progress.
The signal to remember
The noun after much or many usually gives you the grammar signal.
Questions is a plural countable noun.
Time is uncountable in this meaning.
Applications is a plural countable noun.
Information is uncountable.
What to notice
Countability in English is grammatical. Some nouns name things that can feel like separate pieces in real life but are still uncountable in standard English.
employees, applicants, reports, questions, meetings, changes, products, invoices
time, money, information, progress, experience, feedback, equipment, work
Watch the small words
Words such as too, how and so can appear with much and many, but the countability decision stays the same.
Complaints is plural and countable.
Time is uncountable here.
Participants is plural and countable.
Progress is uncountable.
Quick TOEIC check
Choose by checking the noun connected to the blank. This is a local self-check, not a score test.
1. The branch received ___ applications for the sales position.
Correct. Applications are separate items.
Not this time. Much is used for one total amount, not separate applications.
2. The brochure does not include ___ information about the warranty.
Not this time. Information is treated as one amount.
Correct. Information is uncountable here, so much is the correct quantifier.
3. How ___ time will the technician need to repair the machine?
Not this time. Time is one amount here.
Correct. How much time is the pattern.
4. The training session attracted ___ participants from regional offices.
Correct. Participants are separate people.
Not this time. Much does not fit separate people.
A rushed-reading mistake
A translation-first guess can cause problems with nouns such as information, advice, equipment and feedback. Check the noun's English countability instead.
Weak choice
Choose from a broad translated meaning without checking the noun form.
Better choice
Ask whether the noun is plural countable or singular uncountable in this meaning.
Why the mistake can return under pressure
A familiar-looking sentence can tempt you to skip the noun check. Use the same short decision each time.
Use repeated mistakes as evidence
A single missed item does not establish a Learning Block. If the same pattern appears repeatedly across several attempts, review whether you are rushing, translating before checking structure, relying on memorised examples without checking the noun, or losing accuracy under pressure.
You may answer from familiarity before checking whether the noun is countable.
You may rely on a broad translated meaning instead of the English noun pattern.
You may know example phrases but not apply the countable/uncountable rule consistently.
You may know that some nouns change meaning and spend too long when the sentence gives a clear form.
Use small TOEIC mistakes as a diagnostic
If the same much/many error keeps appearing in timed practice, review the decision pattern as well as the grammar. One missed item alone is not enough evidence to identify a Learning Block.
