Question: What year did Fank Meshberger discuss the background figures and shapes?
About the article "The Creation of Adam", section "Anatomical theories".

Candidate passages:
Several hypotheses have been put forward about the meaning of "The Creation of Adam"'s highly original composition, many of them taking Michelangelo's well-documented expertise in human anatomy as their starting point.
In 1990, an Anderson, Indiana physician named Frank Lynn Meshberger, M.D.
noted in the medical publication the "Journal of the American Medical Association" that the background figures and shapes portrayed behind the figure of God appeared to be an anatomically accurate picture of the human brain.
Dr. Meshberger's interpretation has been discussed by Dr. Mark Lee Appler.
On close examination, borders in the painting correlate with major sulci of the cerebrum in the inner and outer surface of the brain, the brain stem, the frontal lobe, the basilar artery, the pituitary gland and the optic chiasm.
Alternatively, it has been observed that the red cloth around God has the shape of a human uterus (one art historian has called it a "uterine mantle"), and that the scarf hanging out, coloured green, could be a newly cut umbilical cord.
"This is an interesting hypothesis that presents the Creation scene as an idealised representation of the physical birth of man.
It explains the navel that appears on Adam, which is at first perplexing because he was created, not born of a woman."
The MacKinnons occupied the house until about the year 1790 at which time they relocated to Corry Lodge in Broadford.
The remains are now used as a sheep fank. 
Daniel Immediato felt that the school district's policy of establishing mandatory community service was in violation of his 13th and 14th Amendment rights.
The school district required that 40 hours of community service be completed to graduate with no exceptions.
Regulations on what could be done for community service were fairly lax, as all work for non-profit organizations with the exception of religious organizations that did no charitable work was accepted as community service.
As part of a mandatory senior-year course, students had to complete a form about what community service they did and how it benefited them, and afterwards discuss it with the class.
Certain goals had to be reached by certain periods of the senior year. 
The opening of the official Carski Rez studio in 2007 in Banovo Brdo marked a new chapter in the label’s work.
Following the release of the Babble Goons album Critical Condition, Skrajb left the group, but continues with Carski Rez as a solo artist.
Taking his place are MCs Earthquake Slick and Bigavac, and DJ Grusm, the only member of Carski Rez who is not of Serbian descent.
They continue to perform in Ottawa and are currently working on a new album.
Another addition to the list of Carski Rez artists is Grema Dži, an MC and producer from Austria, who did most of the mastering work on the Babble Goons album.
He also owns and runs Maximal Studios, a professional recording studio in Vienna.
In 2008, Oblici od Oblaka deo 2 (Cloud Shapes Pt.
2) repeated the success of its predececor, earning Blokovski another demo album of the year title at Rad I Vizija, while the album's leading single "Ha Ha" was voted best demo song (Sqb & The Easst also found themselves in the final round).
Skubi’s side project “Skubi predstavlja Gazda Paju” (Skubi Presents: Gazda Paja – Funk’d Up) was voted as the year’s best EP.
June 2008 saw the first nation-wide release of a Carski Rez album, a compilation featuring all of the label’s artists and titled “Rez 1” in cooperation with the music label Magmedia.
This release allowed for new exposure, including two critically acclaimed singles from the album, “Kosmos” by Skubi & The Easst and “Gengsta Fank” by Mothaphonkin Mjan.
The year ended with another addition to the list of artists – Supreme, from Zaječar, who recorded "Samo Lagano" with Blokovski soon after.
Carski Rez remains active with several new releases in 2010. and 2011, of which Blokovski and his album "Prototip" was the most noted. 
Despite this, the Khmer Republic did not survive the 1975 dry season offensive.
The communist forces had by this point surrounded the capital, whose population had been vastly increased by refugees from the fighting; Lon Nol, who was extremely superstitious, ordered that consecrated sand be spread around the city from helicopters in order to protect it.
Though FANK was by this time fighting with extreme tenacity, and the Khmer Rouge soldiers were suffering from poor morale, malaria, and even higher rates of casualties than FANK, fresh supplies of arms and ammunition from China gave them the impetus to overrun the Republic's remaining outposts.
Proposed peace negotiations repeatedly stalled as Sihanouk refused to deal with Lon Nol directly, requesting his removal as a precondition.
A plan proposed by Étienne Manac'h, the French Ambassador to China, in which Sihanouk would return to Cambodia as the head of a national unity government (leading to the likely immediate defection of a large proportion of the Khmer Rouge's peasant soldiers), failed to materialise.
On April 1, 1975, Lon Nol resigned and fled the country into exile: FANK almost immediately disintegrated.
While Sirik Matak, Long Boret, Lon Non and several other politicians remained in the capital in an attempt to negotiate a ceasefire, the Khmer Rouge finally entered the city on April 17; within a few days they had executed many representatives of the old regime, and the Khmer Republic had effectively come to an end.
During its brief existence it had received almost exactly one million dollars of US military and economic aid a day.
The final area held by the Republic in any form was the Preah Vihear Temple in the Dângrêk Mountains, which FANK forces still occupied in late April 1975.
It was finally taken by the Khmer Rouge on 22 May.
