Le stand a soixante-dix objets.

Because a is the verb avoir (to have), so Le stand a... means The stand has...

Est is from être (to be), so Le stand est... would mean The stand is..., which would be a different sentence.

• a = has
• est = is

So in this sentence, a is the correct choice because the stand is possessing / containing objects.

Le is the masculine singular definite article, meaning the.

So:

• le stand = the stand

French usually requires an article where English sometimes does too, and often even where English might leave one out. Here, le simply identifies a specific stand.

Yes, stand comes from English, but it is also used in French as a noun. In French, un stand usually means a booth, stall, or display stand, especially at a market, fair, or exhibition.

So even though it looks English, in this sentence it is a normal French noun.

Also note:

• le stand is masculine
• the pronunciation in French is adapted to French sound patterns

French standard counting uses a base-20 style in some numbers.

Soixante-dix literally means sixty-ten:

• soixante = 60
• dix = 10
• soixante-dix = 70

This pattern continues:

• soixante et onze = 71
• soixante-douze = 72

This can feel strange to English speakers, but it is completely normal in standard French.

French numbers are commonly joined with hyphens. In modern standard spelling, number elements are typically hyphenated.

So soixante-dix is written with a hyphen because it is one compound number expression.

Because the sentence says there are seventy objects, which is more than one, so the noun must be plural.

• singular: un objet
• plural: des objets

In this sentence, after a number greater than one, French normally uses the plural noun:

• soixante-dix objets

The -s at the end marks the plural in writing.

After a number, French usually puts the noun directly after the number, without des or another article.

So you say:

• soixante-dix objets

not:

• soixante-dix des objets

This is similar to English, where we say seventy objects, not seventy the objects.

The word order is very close to English:

• Le stand = subject
• a = verb
• soixante-dix objets = direct object

So the structure is:

Subject + verb + object

That makes this sentence relatively easy for an English speaker to follow.

A simple pronunciation guide is:

luh stah(n) ah swa-sahnt-deez ob-zhay

A few notes:

• le sounds roughly like luh
• stand has a nasal vowel in French pronunciation
• soixante-dix is pronounced as one number group
• objets ends with a sound like -zhay

Also, the final -s in objets is normally silent.

Usually, yes, or at least more than many other final consonants in French. Because stand is a borrowed word, its pronunciation does not behave exactly like a typical old French word.

The exact pronunciation can vary somewhat, but learners will generally hear something close to stand adapted to French pronunciation.

Normally, no important required liaison is made here.

In particular:

• objets ends with a silent -s
• but the next word does not begin with a vowel, because it is the end of the sentence

Also, between stand and a, French speakers do not usually make a liaison there.

So this sentence is fairly straightforward to pronounce word by word.

Yes, grammatically you could, because possède also means has / possesses. But it sounds more formal or more literary.

In everyday French, avoir is much more natural:

• Le stand a soixante-dix objets.

So a is the most ordinary and expected choice here.

The singular is objet.

• un objet = one object
• des objets = objects

In this sentence, the plural form objets is needed because the quantity is soixante-dix.
