Answer:
Great Britain and France pressured the provisional government to remain in the war.
Step-by-step explanation:
Eventhough it was a very unpopular decision by the Tzar government to participate and fight in WWI the provisional Government, which was left after the abdication of the Tzar Nicholas, was in charge of trying to call for a democatric election, but at the same time was pressured by the allies on France and Britain to continue with the battle on WWI, this decision would eventually weaken the power of the provissional government since 8 months later they´d lost the country to the Bolshevik revolution.
