"Vivono diciotto mesi."

[nekogaijin]

How long do you expect these clones to survive? Well, they live for 18 months. Then they die, and we recycle them as soylent green.

[SpaghettiCorgi]

XD

[Generaliss1]

I think you mean replicants.

[Revilo_N]

Laying hens can live 8 to 15 years, but for the sake of economy, they are slaughtered at 18 months.

[Leigh8724]

This is creepy!

[Undina]

Forse Duolingo parla di insetti?

[JasminMiller]

No, io sono assolutamente certo Duolingo parla di le famiglie della domanda precedente

[QUESTION]

In English, which one is correct grammatically?

A. They live for 18 months.

B. They have lived for 18 months.

C. Both A and B are correct.

D. .....or for better correction, please write your explanation.

Grazie mille.

[janeyd12]

A is correct, speaking about life expectancy. I can't think of a meaning for which B would not be awkward as is... you could use a similar syntax with a qualifier, "They have lived in New York for 18 months," "They have lived together for 18 months," thought if it were an ongoing action, "They have been living..." would be more idiomatic. And if it's not ongoing, "They lived..."

[noctuatacita]

Agreeing with janeyd12 -- A is for life expectancy, B is for age, both are grammatical.

[GoodLordigans]

Is this more likely to be saying that something has been alive for eighteen months, or stating something's life expentency?

[mukkapazza]

More for lifespan. Otherwise you might see "da":

• I gatti vivono pochi anni/Cats live for a few years
• Viviamo insieme da pochi anni/We've been living together for (just) a few years

[Katzenperson]

Mille grazie.

[bvenus]

how come the sentence does not include the word 'per' (for)?

[Flygirl8]

Some Italian verbs can have "for" following.

Lui chiede una mela: He asks "for" an apple.

Examples:
- chiedere: to ask (for)
- pagare: to pay (for)
- cercare: to look/search (for)
- aspettare: to wait (for)
- vivere: to live (for)

[phunanon]

How would you say "He asks an apple." in its literal sense? :)

[radiabetic]

I could be wrong, but my guess would be "Lui chiede a una mela."

[Jenni7771]

Who lives only eighteen months?

[Macossay]

Plants, insects, very small animals, and animals bred for market at a young age.

[jamesjiao]

Ok, can someone explain this to me. In the previous exercise, I lost a heart for missing the 'per' in 'corriamo per tredici minuti' (can't remember the exact numeral, but you get the idea), but here it's missing in the default translation (vivono diciotto mesi). Why is that? Why can I not say 'corriamo tredici minuti'?

[EdaSaydan]

Please refer to the Flygirl's answer, which explains why.

[Athmel]

If I had to guess it'd be that corriamo means "we run" and not "we run for". Although it does seem arbitrary.

[AnthonyBar23923]

why no "per"? Grazie!

[EsperantoEthan]

This is so sad! Let them live!

[RedheadedRogue]

We are as mayflies.
